yeah I have that. but when I launch it the message appears: "Windows 2000 not supported"...don't know what the deal is...
did you run it in safe mode INSTRUCTIONS: 1. Restart Windows and login to Safe Mode with an admin account 2. Run this utility in SAFE MODE and follow the instructions 3. Reboot your computer if you did and it still dont work then i dont know try a differn't one
Changing the mouse rate would depend on your mouse... Have you tried doing it through windows... Goto your control panel > mouse > hardware > properties > advanced settings... You can change the rate there to the highest that your mouse supports....
