"This OEM Database Cannot Be Opened With This Application"

[Mikey]

I just got this message when trying to open a project I'm working on.
"This OEM Database Cannot Be Opened With This Application"

I've tried launching 2k4 manually and opening it from there, but I still get the same message.

XP/SP2

Any suggestions?
