I know this is a relatively common error, and according to the internet, there's not a single solution.

Is there any first step I should take to fixing this problem?

More information:
I've installed the trial of Adobe After Effects CS5. I launch the program, it loads all of the components, and when it hits "Initializing User Interface" an error message comes up. It says "Crash in progress," and for some reason seems to describe a problem with dynamiclinkmanager.exe. Pressing OK tells me to contact customer support to fix the 0 :: 42 error. It's not a problem with my computer's processing ability.

What do I do first? Is my computer forever unable to use After Effects? Will CS4 work instead?
