Can't crack anything!
Same here.
Same error for me ; GTX 980 on Win 8.1, on dictionnary attack, whatever the algorithm. ; driver 359.06
Back to v1.37
Can confirm this issue w/ GTX950 on Win10, driver 358.91
The issue has already been confirmed enough, and is on github :

The move to github is a bit recent, but try to report bugs here from now on.

Thanks by advance.
Shall we wait for a v2.01 ?
Likely, yeah if using nvidia gpu, stick to previous version or wait for 2.01.
(Issue has been fixed and should be merged soon)

Edit: Release is up. Closing thread.
2.01 is up
