My computer went bad, trying to recover Quick time 7 pro without buying it again.
the serial number is contained in the purchase receipt sent by Apple.
Same problem.. After a clean install, trying to reinstall qt7 pro, but it does'nt seem to accept my serial... Came with final cut studio...
See my answer in your other post.
Final cut studio will register Quicktime as Pro version automatically as part of the installation process
