CR Viewer throwing exception randomly

[bearley]

Here goes.

Have a VB .NET application that we are in testing on. It uses a CR9 report and the activeX viewer for display. Installs and runs fine for a while. At some point down the road it starts throwing exceptions. At that point no matter what you do it won't display/print the report. Only fix so far is a reinstall of the application and dependencies.

Visible error is as follows.

Error in file <"rpt file location">. Failed to load database information.

Application logging throws these errors.

So it looks like the engine is having some problems. No idea what is going on. Copying a fresh copy of the rpt file in the app directory doesn't help. Not listed in CR's KB. Believe me I looked.

So if any one has a solution for this problem you have no idea how appreciative I would be.
