I downloaded this miner Friday night, first miner I could get to actually work as I just recently started getting into this. I was getting ~25MH/s with my MSI 470 Gaming 8GB using the normal one, then went to the best which includes the --asm. Speed went up to  ~32.5MH/s with slight OC to 1290MHz on GPU and to 1700MHz on the memory. Tried to use it today and kept crashing. I downloaded it again to try and start fresh. Hopefully it will work again.

ETA--- I was using Crimson drivers Friday night, and decided to upgrade to Adrenalin last night, so that may be the issue.

ETA Part 2--- I screwed up. Had it at I- instead of -I. Works fine now.

try adding

#define ulong uint64_t

or just replace ulong with uint64_t
