if it's the one with the MyFunCards toolbar download, i had trouble with this, too.
uninstall it TOTALLY, then go through add/remove programs, just to make sure it's fully removed. then go in to your c drive to kill the file folder (if i remember correctly, i had to remove the firefox extension from my firefox extras menu, then uninstall it via add/remove programs, then delete all the folders asociated with it)
then, once it's uninstalled completely, redownload and install it. though if you don;t want to, i don't blame you. it's a lot of hassle to go through for 22 AP
