Same here, just crashing randomly. All started happening after that sh/m lowering. Worked like a charm before.

I just got into this mining thing so I'm a bit of a newbie. I did edit the "edit_me.bat" and tried to execute the "cudaPTSwin.exe" but that just closed in 0.5 sec only showing me instructions. So i executed "edit_me.bat" and now it seems to be working fine. It finds collisions and submits shares. Is this good? I seem to get around 1625 c/m on my Nvidia 780GTX. How fast does 1625 c/m get me 1PTS? How do I calculate the coins from c/m value?
Any help appreciated!
