Error opening item mall

I have a similar problem if I simply try to open the item mall. If i try to click on my item mall icon it says Connection Error 0. I have not any errors in sql profiler or logs.
I execute cash.sql without any problem. I update data/Cash.SData. I did it many times before. Where is my problem?

well thats not a error report we would need to help u. first of all do u use ep6 server files? if so stop using them they are bugged as hell and as a newbie u wont be able to get along with them. second if u dont use ep6 server files post us ur loggs from ur serverfiles /psm_client/bin/loggs

I'm using ep4.5 server files by omega. I have not any errors or warning messages in logs.

Fixed. It's very very stupid bug.
"Version" field in the config.ini should contain "English", not my locale.
