Invalid product key

i'm trying to get help online or chat from microsoft and enterting my product ID for the upgrade i made from windows vista to windows 7 home is saying my product id is invalid which is ____ because i activated it and it said activation was successful.  i rebooted machine and tried again.  looked at SYSTEM to see what product key was entered and it still has old one.  entered new one again, activated, AGAIN, sucessfully and still this product key is not working when i enter it into the help forum.
I need help because windows 7 keeps recognizing an unknown device usb - on and off and on and off and on and off. i have disabled it, i have deleted it. it keeps coming back.  AND media center is not working. keeps looking for a freaking tuner - it will work on reboot but then if it goes to sleep or is on for awhile it stops viewing LIVE TV (which i'm getting from my satellite stb hooked up). have to reboot and often reconfigure the TV signal to get it to work - and that is if it agrees that the UNITED STATES is the right region for media center to operate in!?!?!  i'm losing my marbles please help.

can i just go back to my old system
