I have Windows 8.1 64bit and CNTLM version 0.92.3. It was working perfectly on my machine before it stopped working 1 week ago. The service still starts correctly but when i use cntlm proxy this message shows up in firefox:
The proxy moz-proxy://localhost:3128 is requesting a username and password. The site says: "Cntlm for parent"
What could be the problem, i have not changed any settings in cntlm.ini. it is still in the same state when it was working.
