I'm trying to open some older projects (Logic 6, and even earlier). I've been told that in order to open them I need to use Logic 7, save, and then they'll open in Logic 8. However, Logic 7 won't open anymore, it hangs up during the start process while scanning the AU plugins. The one that it hangs up on is the Native Instruments B4. I tried removing the B4 and B4 FX files from the components folder, but that didn't work. There is no option to abort the AU scan (as there is in Logic 8). What do I have to do to open these old projects?
