I have rebooted laptop multiple times. iTunes will launch per usual, then immediately locks up into color-swilry-busy mode. Force quit shuts down the program, yet the iTunes icon remains when I splat-Tab between programs. I shut down iTunes [association/cooperation whatever it's called in LimeWire] but iTunes still refuses to work. I will try the reboot in Safe Mode & Repair Permissions and try to reset things.

Makes me wonder about downloading PRO. (Also having grief from another third-party app I downloaded for a fee and doesn't work. Maybe I should stop trying to "think outside the box" with third-party developers?)

Thanks for the help so far. Will advise of progress, if any.
