I installed it from the original discs. I went away for about a week and came home and tried to open it and got this message. I've never had a problem before until about 2 weeks ago.
Here's the image of the error:
Just got this same message. Happens about 4 times in a row when opening a new audio file. I haven't used the app in over a year. I suppose all the MacOS X updates in between have hosed something up.
The last thing it did was suddenly go silent in the middle of playing a track. The meters went dead as well. Time to move on I suppose.
