I am repeating myself already. If it doesnt work there are 2 steps you can try.

1) Download Test Log DLL, run for few hours send me nodevfeeLog.txt
If Test Log DLL doesnt work (no nodevfeeLog.txt)
2) Download Error Report DLL and message box should appear with error number.
Otherwise I cant help no more.
