Logic And Uneditable Waves?, Recorded audio tracks, Guitar, vocal etc Options

[Dreadman718]

Ok what have I done? And how do I fix it? HELP! OK.. I'm working on a track in LOgic Pro 7 and things are great! So just for shits and giggles I decided to mess with effect plugins and Mastering inserts. It seems after I did this I can no longer access waves to edit? Ok but now the strange thing. If I shutdown Logic, restart it and go to another project I can edit the waves there. Then I go back out and into the projrct I couldn't edit wave and the first wave I can now edit. But when I go to another part of that same project. The little rainbow circle spins and the screen just BLINKS and no Sample editor window? Then I go back to previous project that worked and I can't edit waves there either? Sounds to me like a currupt file, but I'm using a G5 dual 1.8 not some flaky PC? Anyone have a clue? I don't.
