While working on a new report, I have right-clicked on a placeholder and selected "Expression" (like I have many time before) and now I get a wierd Microsoft error simply stating "Undocumented Error". Showing message details produces the following ...
Could not load file or assembly 'Microsoft.VisualStudio.TextManager.Interop.8.0, Version=8.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' or one of its dependencies. The system cannot find the file specified.
This does not appear to be report or project specific. None of my projects or reports will allow me to edit expressions. Everything else in BIDS seems to work (even the reports run).
Tried Googling with no luck. Anyone have any idea?
