ive been running comodo for along time this just happened in the last few days, also when i try to download the program from any link in this forum it says server not found

Same problem here. I have the same setup (Win 7 X64) and have CIS version 5.3.181415.1237 X64 installed. The last AV database update was on 3/9/2011 at 2:51:09 AM. Now I get a message saying that the program failed to update the database and advising me to check my connection and try later.

It now says its up to date :))) any admins have any insite why it was not updating and why it was saying access denied ,thx ion advance.
