Ok. Lots of times when issues along these lines arise, often registering again with your username and password and rebuild collection will fix them. But not always.
You mentioned you have a new computer. Are you seeing any error messages like, 'Too Many Installs' ? This is probably the most likely culprit after so long away. There's a forum thread specially set up for these. Post your problem and a Moderator will help you. Look under 'Bugs & Fixes'.
If you've checked all of the above, then please be more specific with what you actually did when you came back. Screencaps of your software settings can often help a great deal :)
Oh. And welcome back, old timer! ;)
