Been using logic 8 on my Power PC and I have 9 on my Intel Mac Book Pro 17" for a while now and this is a first for me. I was placing several loops into the loop browser from my Mach 5 folder. Noticed that these were .wav files. I think this caused the problem. Logic chocked and gaged! Had to force quit and now it does not restart. I've reloaded it several times after removing prefs and receipts and main app. Still won't start. Using this on: Model Name: Power Mac G5 Model Identifier: PowerMac7,3 Processor Name: PowerPC G5 (3.0) Processor Speed: 2.5 GHz Number Of CPUs: 2 L2 Cache (per CPU): 512 KB Memory: 4.5 GB Bus Speed: 1.25 GHz Boot ROM Version: 5.1.8f7 Is there a way to do a clean uninstall? I must be missing something. Help me somebody!!!! Can I just install the app or should I do the BIG install that takes several years?
