Lockedout

ok i have an office keyboard made my micro inoventions, and i installed the web office to help unlock the capabilites,but everytime i played a game it came up with a list id have to close out every time. so i uninstalled it and it uninstalled my keyboard and it restarted my computer and i have a windows xp password, and no keyboard works, do you think im just in big trouble and im locked out for good. plz help

i got the problem fixed, all i did was when my comp first turned on i held f3 because its the default key and works no matter what,and i recovered my comp so im all set, but thanks for the suggestion. im only 15 so the comp didnt have nothing to worry to much about on their but thank you again.

i dont have one with a usb but ill prob try walmart, but thanks dude if this helps ill like dance lol.
