Hi,
I'm hoping someone can help me get BFGminer working with scrypt.
I've gone through all the documentation, all the posts I can find on here and other places on the web about getting scrypt running in BFGminer, but I still can't quite get it to work.
Using version 3.1.1 (which has scrypt compiled into it), I can connect to a pool, and send of a get work request, but then things seem to fall apart.
I'm running an MSI 7970 card and I'm launching BFGminer with the following batch commands:
setx GPU_MAX_ALLOC_PERCENT 100
setx GPU_USE_SYNC_OBJECTS 1
bfgminer --scrypt -o pooledbits.com:8337 -u BLANKED.1 -p x -I 13 --shaders 2048 --debug 2>log.txt
The following is what gets dumped with debugging turned on:

At this point, BFGminer simply closes down.
Can anyone give me any advice/help/suggestions about what is happening and how to get it to work.
Thank you very much in advance.
Eric
