XTrap ERROR. Please HELP!
 

Here is my details:

OS: Windows Vista x64 SP1
Processor information: AMD Sempron 3000+ (Real: 1,8 GHz)
RAM: 1 GB
Graphics information: NVidia GeForce 6600, 128 VRAM
Nature of problem:
After installing and updating of launcher and game when I try to log in Fiesta
XTrap shows this error:

and then all windows disappear in some seconds...

More details:

I have a connection through proxy server which is installed on other PC that is connected to the Internet by ADSL. And maybe XTrap just can't connect through my proxy (I tried Proxifier, Freecap and without them). The client itself connects through Internet Explorer (and IE works well with my proxy).
I also tried to use compatibility with Windows XP SP2 mode.

I'd like you to tell me how should I deal with this XTrap error.

P.S. Sorry for my English. I'm a foreign otaku ^^
