You could try it from the DOS prompt and see where you're going wrong. The batch file method may close the window so quickly you can't see the results.
1) Go to start- > Run -> type in "cmd"
2) go to the directory (eg. "cd c:\cgminer") cd means change directory
3) try "cgminer.exe --scrypt -o whatever -u username -p password"
Add on the extra parameters a few at a time. Also the -u and -p that you have as xxx, I trust that you have actual username and password for these and the 'xxx' isn't what you're actually using. Had to ask.
