Timeline buttons grayed out

antivirus programs are often problematic, I don't use any protection on my edit PC and instead use a dedicated PC with protection for email and browsing

one antivirus program that works fine with all versions of EDIUS is Nod32 Antivirus 8 with EDIUS excluded like the attached

It is best to turn off the antivirus when installing Edius. Once you get the program installed you can exclude it from your antivirus.

thanks and a few more questions

Thank you for the quick response. I chose to finally just update Edius (long overdue) from 5.01 to 5.10 as the first step in the process of getting to 5.51. Once I updated to 5.10, it started working properly. I then went on to install 5.51. No more having to work with huge AVI files it seems. Can I edit using the files I import in? Is the quality just as good as with AVI? One other question: download page strongly suggested installing a 3D PnP also. When I tried, this Norton Security blocked and removed the file cts3dpinp.tpi. It says the threat name is WSReputation1. Do you know about the safety of this download? Is it that important of a file?

If the cursor is black and has a lock icon on it when you place it on the timeline, it means a dialog box is open somewhere that needs to be closed before you can do any more editing.

The only timeline button that can be clicked on is STOP. Entire timeline is frozen even if I just try to click another place on it, it takes a minute to even get to the new spot. Any suggestions. Edius 5.0
