Help PLEASE!! Hard button issues!!!

[viperboy]

i installed vito buttonmapper and it was causing some issues so i went to uninstall and it said it needed to soft reset, so i did. when it booted back up, none of the assignable hard buttons did anything except for the messaging button that opens windows live messenger. i dont know why it does that, as i never had it set to that and all the buttons are assigned to what they should be in settings > buttons

any other hard button press comes up and says "the file 'buttons' cannot be opened. either it is not signed with a trusted certificate, or one of its components cannot be found. if the problem persists, try reinstalling or restoring the software". so now what? i uninstalled a third part app and it uninstalled the hard button software!!! what can i do? thanks
