It worked yesterday!?!

Since then I've changed the permissions on my user files, and my wife's user files so we can use the finder to access each other's accounts. I made no modifications to the Applications folder!

Now when I click the 2142 app it hops, then stops, ... all in less than a second. I have removed all traces of BF2142, reinstalled and even applied the patch. It simply won't run.

Please help.
