If you have the disc, the best thing would be to uninstall and reinstall.
To uninstall go to Start>Control Panel>Add or Remove Programs. look for the program and uninstall.
If you don't have the disks, then you may be in trouble. If they limit your installations, you should be able to call them and tell them what the problem is. They should grant you another "key", if it's necessary.
