Thanks. We pretty much figured out that is was corrupt, and were looking at a restore, however it means losing several SIMS which is not going to be popular amongst some owners. (since my team went 0-8 during that time, I'm pretty sure I won't be too disappointed)
However, I am curious as to how this occurs, and is it likely some kind of attack?
I am a programmer/developer and would gladly put some effort into a program that could export, "clean", and restore the Database if I could get some help from the game developers on a way to do it. I work constantly with SQL Server and ACCESS databases and would gladly write a utility to do this.
