I just migrated CS6 and LR4 to a new iMac. I then re-installed CS6 from disc because the licensing didn't come over. So far so good. But now in LR4, when enter CMD-E, or choose "open in CS6" from the Edit menu, nothing happens. The file does not open in CS6.
Not sure what I broke or how to fix it but I need it fixed ASAP.
