Can you launch Preps by itself outside of Prinergy? Also, what version of Preps are you using?
Also, Snow Leopard does not have AppleTalk so that could possibly be playing a role in the problem.
And what version of Prinergy?
There is a small bug in Prinergy 5 that can give you fits if you are connecting to the Prinergy network shares as SMB via the IP address. The solution is to use the name of the server instead of the IP address.
