Quicktime in After Effects is not working on my macbookpro OSX 10.7.5. I would like to unistall and re-install. Will my serial number still be valid after uninstalling? I have already installed CS5.5 Master Collection 2 times (for my 2 computers). Thanks. Théo

yes, as long as there's no significant hardware change, the installation/activation is not counted as a new one.

but after uninstalling, clean per Use the Adobe Creative Cloud Cleaner Tool to solve installation problems and then reinstall.

and before doing all that you might try resetting your preferences:
