Did you buy QT pro from Apple's online store? If so, you can log in to get the key and re-enter it.
If you didn't buy it from Apple's online store, the receipt or whatever should have the key on it.
If you didn't buy it at all - Don't pirate QT Pro. If you don't think it's worth $30, you can use the free MPEG streamclip which uses QuickTime APIs and does nearly everything QuickTime Pro does but with a less pleasant (IMHO) interface.
