Logic Pro 8 loads up blank...

Question

Hello, I've encountered a problem with Logic Pro 8 loading up blank when attempting to open a session. All of the recorded material is still there and plays but I can't see anything other than the tool bar up top (inspector, Settings, etc). Everything else is wiped out with the beige color. I'm relieved to know that all my audio is safe and secure but with no way to edit, record, and otherwise resume my production, I'm somewhat troubled.
Although this may be irrelevant information, I'm using a Focusrite Saffire Pro 40 via my MacBook Pro running Logic 8 and running my sessions off a OWC Neptune 160GB Ext HD via firewire400>Saffire>MacBook. I've tried troubleshooting extensively including: Closing project and reopening, Restarting Logic, restarting my computer and hardware, checking my Saffire MixControl, checking AMS, among other things. Any session I try to open right now comes up blank as I mentioned. Which leads me to believe that there is a graphic display issue. Perhaps an essential Logic file got deleted/corrupt that is necessary for proper load up and display?
I was just working in these sessions last night without a problem. Saved everything, closed project, quit Logic, quit Saffire MixControl, ejected my HD from Finder, shut down hardware. I don't understand why I'm all of a sudden having this problem. Thank you for your time and help!

Answer 1

if someone were to want to do a reinstall of Logic 8, would they be able to find equivalent Logic 8 files on their system?
According to this Apple tech note, yes.
Although things changed with 10.6. So it's not a L8 vs L9 thing. It's a 10.5 vs 10.6 thing. The OP has 10.5, so he would find those files.
My feeling is that it's not an across-the-board problem where any song he works on will become corrupted; it might have to do with something specific to those projects which become corrupted
Right, I understand this is possible, but he said (if I understand him correctly) that the problem happens even with a new project where all he did was "recorded some material, drew in some automation, then closed the session." I'm surprised that a project is getting corrupted so easily. I haven't seen L8 or L9 corrupt a project so easily, but maybe you have. Then again, maybe he'll tell us about something peculiar he did to that new project which will explain the ostensible corruption.
