My iPhone can't open some apps?

Right after installing the 2.0.1 software, some apps wouldn’t open, after synching to iTunes some more started working but some are still useless. Whenever I try opening some apps it displays the message “The application “_____” cannot be opened.” I synced it to iTunes and backed up. Anyone have the same problem?

List of apps that don’t work:
Beatmaker
Trism
Super Monkey Ball
Motoracer
Palringo
Shazam
DizzyBeeFree
Any help?
