Hope someone can help as i'm at the tearing my hair out stage. I had the evaluation copy of sql server 2014...It expired so i bought the developer version from microsoft online store..Downloaded and installed ok...When I went to use it however through start menu and sql management studio my problems began. I get the popup telling me that the expiry period is up and directs me to buy a license key. I then try to use the upgrade wizard to use my product key and it says invalid key. I uninstall the shared components...still same message. I uninstall evaluation instance - same message. I have now one instance but still can't access the management studio and am getting the same message (invalid key). I guess I need to change something in the registry but what?
hope someone can help
