Best way to figureout why a report wont load in the designer?

[sitefinitysteve]

Does anyone know how to figure out why a report might not be loading in the designer?

I'm getting this generic error...

To prevent possible data loss before loading the designer, the following errors must be resolved: 1 Error Why am I seeing this page?

This looks like the good old "just let VS sit down for lunch or sleep with Windows" error I've been getting in Windows Forms since .NET framework came out. In my expertize, closing the form (in your case designer) and reopening it should do the trick. If it does not, try rebuilding or if stubborn you can close VS and reopen the whole thing.

Cheers!
