[Solved] JDownloader close alone

I have this problem since I change my computer, now is Windows 7 OS and is x64 and I dont know if that maybe is the problem but the program close only passin the time, sometime pass 15 mins, and sometimes is after 8 hours, but, like a lot, I keep my computer working when Im studing or somewere.:blink:

Every time that JDownloader close alone creates and .LOG in my Desk, and I adjunts the last 2 here, I really need help to know whats the problem,

Thanks.

Notes:

-I have avast! Free (I always have that, and I dont think thats the problem)
-When JDownloader closes alone I normally dont have other programs running.

SORRY for my bad english, is not my native language
