Garena Messenger (Garena Plus) and Ubuntu 12.04 not working

Hi, i'm new in this forum but i always referred to you when i was looking for answers about Wine's issues! :) But now, after searching in many posts, i didn't find a way to fix my issue! I've installed the last Garena client (1.29 beta) on my Wine 1.5. The installation completes without any problem, i also got to get in the messenger window, but when i choose LAN to get in the Server Room it stops working: sometime it says Internal error received, invalid parameters; sometime it just close showing a report window.. How do i fix it? I have Ubuntu 12.04 x64 and lastest Wine release, what shall i do? I hope someone will help me >.< Have a nice day :)
