I had a serious hard drive failure recently where all data was lost. I had purchased a key to upgrade the QT Player to QT Pro prior to this incident. This was just a few weeks ago.

Is there any way I can use the key registration I had to upgrade the current QT Player again?

I tried and it wouldn't work. Do I really have to re-purchase another upgrade/key code?

Thanks in advance...

oh no, make sure you enter it all EXACTLY as it was sent to you, it is very very picky about spelling, and if all else fails, call apple

Mine worked with the new QT5. You shouldn't have to repurchase.
