Some workstations not allowing Adobe Bridge CS3 application launch

Question

Hi all.
I'm pretty new at helping manage a MIDI/art lab at a high school campus (not new to Macs, but new to this issue).
We have a student login for an art class where students should have complete access to the Adobe CS3 suite of applications. The account is logging in on a server, running apps on the local hard drives, and an entire class of students all log in at once. We've tried to keep all the iMacs current in terms of Adobe updates and other software updates.
The problem is this: there are four iMacs which - in spite of all updates being equal, and the fact that all users are logging into a network account (thus all having the same set of rules, permissions, and restrictions) - fail to allow students to use Adobe Bridge. At these four stations, launching Bridge gets this error:
+*The Application "Bridge CS3" is not allowed.*+
+"Bridge CS3"is not on the approved list of applications. Contact the person who set up your account for more information.+
We've tried several things, including running Adobe updater (again), Apple software update, and resetting/trashing Bridge's prefs.
Again, every user should be experiencing the same permissions and restrictions, and this issue seems to be tied to hardware as it only applies on four of the iMacs. Logging in as an administrator or a local account with full permission allows clear access to Bridge. However, we need the Art Class account to work on all our stations as students use Bridge regularly for class.
Any input and suggestions will be greatly appreciated.
(By the way, these are Intel iMacs running, I would presume, Snow Leopard. The model and OS info shown below are my machine, not the lab stations.)

Answer 1

Curt Y. Thank you for your answer.
It was only Bridge who was crashing. It failed to load and Windows was giving an error message.
I tried your suggestion, and resetting all options in the reset window it now loads. It was as simple as that.
