tidstein,
I'm sure you have tried rebooting your PC. If this did not solve the error try repairing the installation of the DSC Module from Add/Remove Programs in the Control Panel.
Citadel 5 is the database portion of the DSC module. It is dependent on several other components that should be installed/updated by the DSC Module installer. Another component that Citadel depends on is Microsoft's MSDE (http://www.microsoft.com/sql/msde/default.asp). This shows up as sqlservr.exe in the task manager (This component is automatically installed when you install the DSC Module). Citadel must be able to start this service in order to run.
Let me know if you were able to resolve this issue.
