ClassView... restore content after DevStudio Crash?

While I was writing C++ 6.0 code, it happened a couple of times to me, that the DevStudio crashed, when I pressed F1 to get into the HelpSystem. There was a message something like "insufficient memory to perform this task"...

Anyway, as a matter of fact, when I restarted DevStudio and loaded my current Workspace, there was the Message like
"Cannot access ClassView information file, ClassView information will not be available"

By deleting the .CLW file from my project directory, the classwizard created a new one but it didn't update the ClassView.

does somebody have a clue how to recreate the ClassView information ?
