I installed After Effects CS3 on my mac running snow leopard 10.6.4 I also installed the update for After Effects. However it will not run, everything is activated and Adobe says the activation is fine. However the discontinued phone support for CS3. What happens is the program will launch and show up in the dock but before the splash screen even launches the software will just crash and shut down. I seem to remember this was an issue when i installed this on my desktop but for the life of me I cannot remember what I did to fix the issue.
