My wife's EMachine PC came with an OEM load of Vista Home Premium installed on it. There was no media included.

We had to install XP Pro on the machine because of some classes that she was taking. Now that said classes are over with, she wanted to go back to Vista.

Unfortunately now we couldn't do a restore back to the original factory load - something got hosed up when we went to XP.

Since I had the Vista serial number that was on the label on the back of the machine, I borrowed my friend's Vista Home Premium retail DVD and installed from that.

To my dismay, now we can't activate with Microsoft - I assume because of the mismatch of OEM and retail.

If I call Microsoft to activate, am I wasting my time? Will they actually be able to assist with this situation?

Thanks everyone!
