Your prefs may be messed up because the patches set a few parameters differently. Check Todd's blog for a few pointers. Anyway, as a first always trash the prefs (Users:Bush:Library:Preferences:Adobe:After Effects:9.0). Furthermore, if you have used the disk caches, clean them out, too ( by default in Users:Bush:Library:Application Support:Adobe:Common). And lastly, of course remove the AE_OpenGL.plugin, if need be (Applications:Adobe After Effects CS4:Support Files:Plug-Ins:Extensions). Even if you say you don#t use any scripts, you may still need to trash customized workspaces, also in your Preferences directory.
Thanks for your reply!
I trashed the prefs, cleaned cache, removed openGL plug and app still crashes as described above. Any other suggestions?
There are no Mac Pros with Core Duo processors. You meant a Macbook Pro?
The Perian preference panel has an option to unistall it (and then install it again if you want).
It can't hurt doing that, then restarting the computer to make sure Quicktime is not using it, and try again.
If it's not the culprit, enable Perian again in System Preferences.
By the way, what video formats/codecs are you source files (if they are video files at all?) Just to check if it can be a conflict with the formats Perian handles (many of which overlap with AE's own importers). It's just a guess, of course.
From your description, looks like AE is not being able to write to disk. Did you try repairing permissions with the Mac OS Disk Utility?
Ran Disk Utility. It fixed a Volume Header problem. Repaired permissions. Uninstalled the AE demo app. Installed Production Suite. Ran the massive 1Gb update. All is well in After Effects land!
Thanks to all for your help!!!
I am glad it's all working now.
