Hi,
sometimes maybe 2 or 3 times a day one of the swtor just disappeared/closed and it doesnt matter if i'm playing 2 or 4 accounts. It happends for about 2 months already. Sometimes everething is ok maybe a day or more.

I have Windows 7, 64 Bit, 16BG, i7, geforce gtx 580

I really apricate for the responce.
Thank you in advance.
