I am trying the following and it is not working:
"C:\Users\atx\Documents\guiminer\cgminer\cgminer.exe" --scrypt -u jack -p password -o stratum+tcp://127.0.0.1:3333 --gpu-platform 0 -d 0 -w 256 -v 1 -I 13 -g 2 -l 1 -T --thread-concurrency 8192
try '
http://127.0.0.1' instead of 'stratum+tcp://127.0.0.1' unless you have a local stratum proxy running
