Yes I did that. Actually I made a reinstall and now I do get a bit further. I can now go into the chat pannel (normal user).
But I still cannot login to the Admin Panel. I get the following error:

PHP Warning: fetch(d:\Domains\domain.com\wwwroot\forum\chat\inc/../templates/templates_c\%%AC^AC1^AC1385FF%%admin_index.tpl.php ) [function.fetch]: failed to open stream: No such file or directory in d:\Domains\domain.com\wwwroot\forum\chat\inc\smart y\Smarty.class.php on line 1251 PHP Warning: fetch(d:\Domains\domain.com\wwwroot\forum\chat\inc/../templates/templates_c\%%AC^AC1^AC1385FF%%admin_index.tpl.php ) [function.fetch]: failed to open stream: No such file or directory in d:\Domains\domain.com\wwwroot\forum\chat\inc\smart y\Smarty.class.php on line 1251 PHP Warning: fetch() [function.include]: Failed opening 'd:\Domains\domain.com\wwwroot\forum\chat\inc/../templates/templates_c\%%AC^AC1^AC1385FF%%admin_index.tpl.php ' for inclusion (include_path='.;d:\php\includes') in d:\Domains\domain.com\wwwroot\forum\chat\inc\smart y\Smarty.class.php on line 1251

All the rest seems to work just fine. I can login in VBulletin and then go to /chat/flashchat.php and I can chat away.
I would very appreciate if one has an idea how I can access the admin panel

Thank!!

Looks like you need to make the templates_c folder writable (chmod 777).

Thanks for the mod.

I'm not sure whether to perform step 3 or not. What exactly does this option do?

Redirects them back to the index page if they click on Flashchats logout button.

I get the same error:
My prime proble is that when I try to open chat a it:
Load setting OK
load chat main window ok
starting chat system...
Then I only get a glue screen with no content.

I can access the Flashchat admin panel okay but whenever I try and run flashchat, either direct or via my forum, I get this - these loading messages then a blank screen with no content.
The "Starting chat..." message seems to jump out at 30%.
Re-installed twice and still the same error.
Any ideas?

As the first post says ;

With all due respect mate - there is no way I would give these details out to anyone.
Cant you offer some advice on how to fix the problem when all you get in a blank background with no content?

There are so many things that can cause that. JFYI, I have fixed many tens of forums who have given me such details over the years. If you choose not to then there is nothing I can do for you.

Could it be the Java server side?

I didnt do it right, can someone tell what to do? I DL'ed the said files and nothing happened.

Thanks
