I've had this problem on and off for some time. Now it is on. I have...
Updated JD
Installed the latest version of Java
Installed the latest firmware to my router
Lowered Max Con to 2 and Max Dl to 3, but have used them successfully larger many times
Changed my download directory
Entered exceptions for java.exe, jdownloader.exe, javaws.exe in Windows firewall
Done all the rest of the things gleaned from 7 pages of this thread
Use Avira Personal Free with no firewall-Crash occurs if guards are active or not
I am on Windows 7
My observations:
The problem is more prone on letitbit, turbobit, uploading
After resetting, the error occurs at the same download position each time, having tried it about 10 times: ie @460.07 KB on one file, 139.73 KB on another, 21.92 KB on another, different amounts on different files
JD is an amazing program. I hope you can get this bug fixed.

Attached is my log file.
Late Breaking Info....
I just tried downloading one of the files from the web page not using JD and the download hung at the exact same place. Letitbit was the site. Could it be something in the module for specific sites or having to do with how specific files are uploaded from specific sites?
