Trouble opening old Logic sessions. Logic Pro 9 suddenly ask for serial in Snow leopard
So I have owned logic for more than 25 years. But the darned vers 9, ask for a serial no now (don't understand what has happened, since the computer I try to open it on is OLD). I can open vers 7.2.2 with my hardware dongle, but I have little idea, where to find the original box, for the serial.
I tried going into Apple Store to look under PURCHASED. But the computer won't log in to Apple Store either.
HELP! I need to get into old logic sessions, as old as from MACOS 9. And creating export files in logic 7, only takes me so long. Without the step through LP9 the files don't do much good in LP10! All help appreciated.
thanks
