First of all, you have to read the README.txt file in your cudaminer folder, and you will find all the info you need for setting up commands and switches.
You can make a shortcut on your desktop pointing to your cudaminer.exe file, and then edit shortcut's "target" line with something like (after cudaminer.exe):
-i 0 -H 1 -C 1 -o stratum+tcp://"YOUR.POOL.SERVER.ADDRESS":"PORT" -O username.worker:password
Only if you input correct data, your cudaminer will start working as it should...
Of course, try to do a "clean install" of nVidia driver before you do anything else...
Thank you for the reply
But even when I fallow the read me and enter it as
cudaminer.exe -H 2 -d 0,1,2 -i 1,0,0 -l auto,F27x3,K28x4 -C 0,2,1
-o stratum+tcp://world.wemineltc.com:3334 -O rbh5081.1:x
I still get the error above
Try as i said, now in full... (just copy/paste this)
cudaminer.exe -i 0 -H 1 -C 1 -o stratum+tcp://world.wemineltc.com:3334 -O rbh5081.1:x
If you make one card work, then just add ,0,0 or ,1,2 as you did...
One more thing... it's VERY important that all "switch" letters ARE case sensitive and that you use SPACES just as it's said.
