I have also been getting the following error on system startup: "AvidStartup has encountered a problem and needs to close"  This problem has been ongoing since first installing Media Composer.

We have no idea to what you are referring. Is there another  post that details  your problem or your hardware and software config?

Is it, perhaps, this one?

If so, please don't start a new thread for the same issue (This one being an installation problem) it  helps us to follow  your information and progress if  you keep it all  in one thread.

Also, please don't type your subject headings in all caps. It's considered rude.
