Hello, To mine Decred, first go join a pool. The pool I'm using is Suprnova. Link: http://dcr.suprnova.cc Create a new account using your email, and set up your new worker at My Account > My Workers. To create a new worker, go to "Add new worker" and fill in the blanks. Your worker name and password will be whatever you want. (e.g. My worker name is Test, and password is 4321. Including my login name as RyanBC, the worker login will be RyanBC.Test" Then, download your nVidia GPU miner. Go to https://github.com/tpruvot/ccminer/releases/tag/1.7.2-tpruvot and click on ccminer-rel1.7.2-vc2013x64.7z. You will need 7-zip to extract the files. 7-zip: http://www.7-zip.org/a/7z1514-x64.exe Now, go to the downloaded file and extract the miner folder by double-clicking the downloaded 7z file. Edit your RUN-DCR.cmd file inside the folder by right clicking it and selecting "Edit". You will see something like this "ccminer-75-x64 -a decred -o http://dcr.suprnova.cc:9111 -u tpruvot.win -p x --cpu-priority 4", change the "tpruvot" to your Suprnova login username, and "win" as your worker name. Change "x" to your worker password. In my case, my login name is RyanBC, worker name is Test, and password is 4321, so it will look something like this "ccminer-75-x64 -a decred -o http://dcr.suprnova.cc:9111 -u RyanBC.Test -p 4321 --cpu-priority 4". Now you should be ready to start mining with your nVidia graphics card. If you have any questions please feel free to private-message me. Thanks.
Interesting, I've never seen this problem before. Since I'm not a developer, I think you should consider contacting the ccminer developers for support. https://bitcointalk.org/?topic=770064
