product key invalid after a year of use...can only access Internet

I am suddenly getting error code 0xC004F050 that my product key is invalid. I bought my laptop in Feb. from Best Buy and Vista was pre-loaded. I installed an update (service pack???) today and used my computer for several hours. Then suddenly this error! I've put in the key several times and nothing! I can't access anything except the internet!! Can anyone help? I'm a teacher and I was typing a test for tomorrow!!!

Thanks!
Wendy
