Dear Claymore:

Out of the blue my miner stop working version ClaymoreCryptoNoteGPUMinerv61Beta
An error window pops up and says NsGpuCNNMiner.exe application error  The app could not start correctly (0xc000007b).  Click to accept and close the program.
I am sure something change in my system but dont know what.
win 7 16 GB ram i7 950 cpu
amd r9 280x  with 14.9 catalyst.

system had been working for 1 month without any problems...

I can run the cpu miner OK but my GPU will not run..  I can mine x11 with same gpu and sgminer_v5_0_mod without any problems, so gpu is ok.

I updated to new version 9.1 but the same error appears.

Thanks for your help
