Midi Timeout [For one session. Cant FIX]

Hey!

I'm using Version: OS X Yosemite - 10.10.2. Logic Pro 9. But problem also occurs when trying to open I open in Logic X.

The MAIN ISSUE is that this only occurs with ONE file. I can open all other files without a problem. But I REALLY need to access this file. Any help? The drivers aren't the problem because everything else works.

Any ideas how to fix this session?

Please and Thank You!!
