I'm on a Powerbook in my dorm room. My iBook is at home. There are some apps on my iBook that I need here. So I logged in with an FTP client and downloaded the .app "folders" (as the FTP client represented them) to my Powerbook. Things seem to be okay, the app displays the appropriate icon and everything. But it will not launch. No error messages. I really need those apps. 
Any help would be much appreciated.
