reinstall of OS...now it's not genuine!!!

[mickeddie]

I just finished reinstalling Vista Home Premium and now on the bottom right of my desktop there is a water mark that says:
Windows Vista (TM)
Build 6000
This copy of Windows is not genuine

Now when I installed this the first time I did NOT have any watermark. This is an OEM version of Vista and it has the COA barcode, a license key that worked fine, and the "proof of license certificate of authenticity with the hologram that says "genuine" going across it (where the product key is".

So why now am I getting this watermark, and how do I get rid of it, and how do I find out if this version really is or is not genuine?

Thanks!

call microsoft and ask them to activate it, have the product key handy because they are suppose to verify it's valid.
