That certainly sounds like strange behaviour if the program has been working fine for a year, and it's just now asking you to register. Have you tried entering your serial key and simply re-registering the software?
Often in order to register you'll need to run Act! with Administrator rights (Close Act! > Right Click the Act! Icon > 'Run as Administrator')
If you're not sure what your serial key is, just drop me a direct message and I can look it up for you in our system.
Hope this helps!

You can check the version you have by going to the menu Help | About Act! and a Window will pop up with the information.
