Need help with tablet tracking mode

Well, the tracking on my tablet is messed up. I want it to use absolute (so that the table is sorta...in porportion with the screen, ya know?) but it keeps using relative. I tried uninstalling the USB manager, but the uninstall file is corrupted. I also tried re-installing the driver, but that's not working either (it gives me a message saying "This program has encountered a problem and needs to close" after the installation has "finished"). Could anyone help me out? Please?
