Just realized CD means change directory...
Hmmmmm
Try the following, use cgminer:
First delete your .conf file in the cgminer folder (back it up somewhere else if you want)
Open cmd, type: setx GPU_MAX_ALLOC_PERCENT 100
Then press return and close cmd. Then open a fresh cmd, CD to your cgminer folder and then input the following:
cgminer --scrypt -o yourpool -u yourusername -p yourpassword -s 2 --expiry 1 --queue 0 --thread-concurrency 8192 -I 13 -w 256 -g 2
Press return and let me know what happens
