[Dmut]

Thand you for taking time to answer me, I've sent an MP tu Han, and I'll be back there if I do not get any news from him ;-)

Since it's a weekend, Han might not answer your PM. I do recommend you to post your question here http://forum.lockon.ru/forumdisplay.php?f=33 , then you will probaly get a quick answers from community members.
PM's are not suitable for questions like these.
