you have to use a conditional if to do that.

open postbit legacy

search for:

<vb:if condition="$show['attachments']">

						<div class="attachments">
						<vb:if condition="$show['thumbnailattachment']">
							<fieldset class="postcontent">
								<legend><img src="{vb:stylevar imgdir_misc}/paperclip.png" class="inlineimg" alt="{vb:rawphrase attached_thumbnails}" /> {vb:rawphrase attached_thumbnails}</legend>
								{vb:raw post.thumbnailattachments}
							</fieldset>
						</vb:if>

						<vb:if condition="$show['imageattachment']">
							<fieldset class="postcontent">
								<legend><img src="{vb:stylevar imgdir_misc}/paperclip.png" class="inlineimg" alt="{vb:rawphrase attached_images}" /> {vb:rawphrase attached_images}</legend>
								{vb:raw post.imageattachments}
							</fieldset>
						</vb:if>

						<vb:if condition="$show['imageattachmentlink']">
							<fieldset class="postcontent">
								<legend><img src="{vb:stylevar imgdir_misc}/paperclip.png" class="inlineimg" alt="{vb:rawphrase attached_images}" /> {vb:rawphrase attached_images}</legend>
								<ul>
								{vb:raw post.imageattachmentlinks}
								</ul>
							</fieldset>
						</vb:if>

						<vb:if condition="$show['otherattachment']">
							<fieldset class="postcontent">
								<legend><img src="{vb:stylevar imgdir_misc}/paperclip.png" class="inlineimg" alt="{vb:rawphrase attached_files}" /> {vb:rawphrase attached_files}</legend>
								<ul>
								{vb:raw post.otherattachments}
								</ul>
							</fieldset>
						</vb:if>

						<vb:if condition="$show['moderatedattachment']">
							<fieldset class="postcontent">
								<legend><img src="{vb:stylevar imgdir_misc}/paperclip.png" class="inlineimg" alt="{vb:rawphrase attachments_pending_approval}" /> {vb:rawphrase attachments_pending_approval}</legend>
								<ul>
								{vb:raw post.moderatedattachments}
								</ul>
							</fieldset>
						</vb:if>
						</div>
					<!-- / attachments -->
					</vb:if>

and replace it with

<vb:if condition="$show['attachments']">

						<div class="attachments">
<vb:if condition="$show['guest']">
Please <a href="register.php">register</a> or login to download attachments.
<vb:else />
						<vb:if condition="$show['thumbnailattachment']">
							<fieldset class="postcontent">
								<legend><img src="{vb:stylevar imgdir_misc}/paperclip.png" class="inlineimg" alt="{vb:rawphrase attached_thumbnails}" /> {vb:rawphrase attached_thumbnails}</legend>
								{vb:raw post.thumbnailattachments}
							</fieldset>
						</vb:if>

						<vb:if condition="$show['imageattachment']">
							<fieldset class="postcontent">
								<legend><img src="{vb:stylevar imgdir_misc}/paperclip.png" class="inlineimg" alt="{vb:rawphrase attached_images}" /> {vb:rawphrase attached_images}</legend>
								{vb:raw post.imageattachments}
							</fieldset>
						</vb:if>

						<vb:if condition="$show['imageattachmentlink']">
							<fieldset class="postcontent">
								<legend><img src="{vb:stylevar imgdir_misc}/paperclip.png" class="inlineimg" alt="{vb:rawphrase attached_images}" /> {vb:rawphrase attached_images}</legend>
								<ul>
								{vb:raw post.imageattachmentlinks}
								</ul>
							</fieldset>
						</vb:if>

						<vb:if condition="$show['otherattachment']">
							<fieldset class="postcontent">
								<legend><img src="{vb:stylevar imgdir_misc}/paperclip.png" class="inlineimg" alt="{vb:rawphrase attached_files}" /> {vb:rawphrase attached_files}</legend>
								<ul>
								{vb:raw post.otherattachments}
								</ul>
							</fieldset>
						</vb:if>

						<vb:if condition="$show['moderatedattachment']">
							<fieldset class="postcontent">
								<legend><img src="{vb:stylevar imgdir_misc}/paperclip.png" class="inlineimg" alt="{vb:rawphrase attachments_pending_approval}" /> {vb:rawphrase attachments_pending_approval}</legend>
								<ul>
								{vb:raw post.moderatedattachments}
								</ul>
							</fieldset>
						</vb:if>
</vb:if>
						</div>
					<!-- / attachments -->

NOTE: this does not work if you show attachments inline. In that case you have to use a hide mod.
