Thank you,

dlouaniswrong forum buddy. That's a dotnetnuke addin.|||Did you look in the server's event log? There is probably more information there that could help you to track down the problem.

And actually, the Data Access forum would be a better place for this post, and yeah perhaps one of the DNN forums, but I don't have a problem with it being here for the time being.
