I looked at the other FTB window and it stated that there was an error --->http://pastebin.com/8hmn5sbG (look at .txt doc that i have added for full log if that link expires) here is the bottom (error) part --->

Hey, thanks i installed java again (for a second time by deleting java completely) and it seems to be stable now and I gave FTB 4.5Gb ram so i think that was the problem and i could not increase it over 1Gb before but now its fine. Thank you for the quick reply and help.
