Have got quite a problem at a customer's site. We installed SBS 2008 Premium in the spring with SQL Server 2008 64-bit on top of that, everything working OK. However I apparantly was not aware that it was neccessary to input the Product key for SQL Server 2008 when running the installation. For the last (probably) six months it has been working flawlessly, however it just stopped, telling me that it expired. When trying to run the edition upgrade, I am told that the Product key is invalid (which should not be the case - I have even tried a couple of different keys (SQL Server 2008 for Small Business Server)).
How am I to proceed?
Thanks a lot in advance for any advice,
Erik
