Problem with After Effects 6 dictionary

I have installed equal versions of Adobe After Effects 6.0 Professional on two computers with OS X 10.3.3. I also have on both computers same version of AppleScript. I need AAE to be scriptable on both computers.

On computer A an AppleScript Dictionary of AAE can be shown, on computer B it can not. If I want to view (over filesharing-network) from computer B the AppleScript dictionary of AAE installed on A, it also can not be shown. This is very strange, isn’t it?

I really need to solve that problem, so does anyone has an idea?
