SP2 Continuously Asks For Activation

I'm about to go out of my mind. I installed SP2 and it appears to work fine except that it installs the trial version that continuously keeps asking me to activate, I have tried uninstalling SP2 and everything works fine, but when I reinstall SP2, it goes right back to limiting my time and asking for activation. I've activated the $!*/# thing about a million times but it never will complete the activation. I don't think I should have to spend $35 for MS support to fix something that should work as advertised.
Can anyone help me out here? I'm at the end of my rope with FSX SP2!
I'd sure appreciate any help you can give me! Thanks!
