Logic X crashes opening Logic 9

Hi Peter,

Thanks for using Apple Support Communities. If Logic X is quitting unexpectedly when you try to open Logic 9 projects, I would suggest the steps in this article as a start:

..or more practically...

Use the Selective Track Import feature in Logic Pro X.. to import each track from your Logic Pro 9 project, one at a time.. to help identify which track (and which plugin which is the most likely cause of such crashes0 is the root of your problem...

This video is for Logic Pro 9 but the version of STI in LPX works much the same way...
