ArcInfo 9.3 -

In a project with datasets stored in FGDB, I get an "Error opening feature class - Could not load the class exntension property set" when I try the Preview tab in ArcCatology and Annotation classes (as shown attached).

I made these Annotation Feature classes in ArcMap with Convert labels to Annotation (with the option to Features in current extent, which I had problem in the past with)... And worse, I cannot even use any ArcToolbox function such as rebuilding spatial indexes in order to optimize these feature classes.

Any help on this matter?
