Over the weekend, Vista Locked me out of pretty much everything on my computer. So I am sending this message with the limited capabilities that Vista will allow. I bought a Gateway Laptop and it came with an Operating System Disc. But today I was notified by a popup in Vista stating that I may be a victim of counterfieting. What does this mean? Does my operating system have an expiration date? Can I fix this issue? I still have my operating disc but apparently it's been "counterfieted". Please help. Thank you.
