Have you uploaded the files as directed in the instructions?

Yes mate.
But i dont understand this...

Example: If you need to copy ./admincp/thehack.php to ./somefolder/thehack.php, it would mean that you need to copy a file, called thehack.php from the admincp subfolder of the package you have downloaded to the somefolder subdirectory of your forum engine.

And i havent got this file...or licence key...

Before you begin, open ./upload/includes/visionscripts/psionic_hide/lc.php using any text editor (such as Notepad) and specify the license key you were provided with upon completion of your order.
When you first access the hack, you are going to receive a key file via your e-mail. The file must be uploaded to ./includes/visionscripts/psionic_hide/. If you do not receive the key file via e-mail on your first access to the hack, login to the client area and download the key file from there.

That is impertinent to the Lite Edition of the hack. All you have to do is upload the contents of "upload" folder to your "forum" folder.

What about all templates modifications?

It happened after i uploaded the xml in products.

Modified the templates,,then uploaded the product xml and i had this message,cant login to the admin panel now....

What can i do now?

Thanks

Everything except for the license key is required for installation of Lite Edition.

You need to upload the .php files as I said.

I have m8.

Sorted it now....Uploaded backup database,will try again later....

Cumps

can this hide attachement?

No, it cannot. It only can hide text within posts.

I have allready Installed this hack,now,if i install the expanded edition,do i have to modify all files and templates again?Or just some of them?

Thanks
