I found a little "error", repeated word, into "tsxviewer_vb4_v1_3.xml".
<h3 class="blocksubhead">{vb:raw server.indicator} <span class="ts_servername">{vb:raw server.icon} {vb:raw server.name}</span> {vb:
phrase phrase_tsx_currentuser, {vb:raw server.usercount}}</h3>
should be
<h3 class="blocksubhead">{vb:raw server.indicator} <span class="ts_servername">{vb:raw server.icon} {vb:raw server.name}</span> {vb:
phrase tsx_currentuser, {vb:raw server.usercount}}</h3>
