Okay, I just now tried it out new, and saw some error messages myself. So, here is what to do.
Open Web-ChatZ4.mrc, and find line 97.
Change that entire line to this...
if (!$exists($shortfn($mircdir) $+ c54\pps.ini)) && ($script(clearmsn)) { dialog -mod xmain xmain }
Next, find line 318. Change that entire line to this...
if ($script(%loaded)) { set %one $1- | set %smilecolor2 %smilecolor | set %smilesize2 %smilesize | $iif($chan,dll DllTmp\Dll $+ $window($comchan($me,1)).hwnd $+ .dll writeln <basefont color="gray" size=2> $+ $chr(160) $chr(160) $chr(160) $chr(160) $chr(160) $chr(160) $chr(160) $iif(!%time,,<br> $+ ( $fulldate ) $+ <br> $+ ) $+ $chr(160) $chr(160) $chr(160) $chr(160) $+ <font face="Marlett">8</font>The File ( %loaded ) Has Been Loaded<br>) | norm }
This should take care of those error messages.
Those error messages won't shouldn't interfere with Web-ChatZ4. So, those of you who downloads the addon should just ignore it. I will post an update asap.
