Final cut won't open on macbook Pro

I have a Macbook Pro with a 2.33 Ghz processor and 4 GB of RAM. It's a great, fast computer. It's running Leopard 10.5.5 and I have have Imovie and the entire Adobe Creative Suite installed and running fine. Final Cut Express installed but won't open for some reason. It may be the version of leopard I have because it's running on my other Mac which has a pervious version of leopard.

Any thoughts please? I'm pretty desperate.

I'm living in the Dominican Republic so I can't take it to a Mac Store...

If your computers are networked, then make sure the other computer is not running FCE. The license checks for that and does now allow you to run on two systems at once.

If that isn't the problem, then check the system logs by using the Console.app in the utilities folder for errors specific to the FCE startup.

I don't have a PCI card. Do I need one to run FCE? I'm not on a server. There's no reason it should not work.

Uh? PCI?

I said networked. As in, if you computers are connected via a wired or wireless network, FCP can understand that and won't let you run the software twice at the same time on both machines. It should tell you that when you try to start the second copy.

Also, check the Console utility for errors.

Which version of Final Cut Express do you have?

My computer is not networked. I'm not even connected to the internet when I'm trying to run it.

I have version 4.0 and I just did the apple update to 4.0.1.

This is the error message that comes up...

Library not loaded: /Library/Frameworks/ProFX.framework/Versions/A/ProFX

A google search found this. The problem was for FCP 6, but identical to your problem. Perhaps a re-install will fix this issue.

I just came across this thread over at macrumors. It is regarding having to start at lease once with the administrator account if you have multiple accounts. Odd, but it worked for the person reporting it.
