Long painful story short, I had to register a client's upgraded MAS200 SQL 4.50 earlier this week with my own keys while Sage took 3 days to get me a new set. I connected to the client's system last night to plug in the new keys...activation is successful. However, upon logging in again, I get a message that says ""your product key is not authorized for MAS 200"". I try restoring, reinstalling, etc. and now I get ""SQL is not enabled"" every time I try to launch, which I cannot find anything on Google or Sage KB for. Does anyone have any ideas at all what I could try next to at least get them back on my keys?
