I have a problem. Whenever I try to create, edit or delete feature classes in ArcGIS geodatabase it gives me an following error: "Error opening feature class." and "Could not add the specified data object to the map."
When I try to open it with QGIS (2.10.1) it is entirely ok and I can even export it as a shapefile and then open it in the ArcMap and it is ok aswell. I have been searching on the internet a lot but I haven't been able to find a solution to this problem anywhere.
I should probably add that it happens with EVERY geodatabase, even if I create a brand new one so I don't think its because the databases are corrupted; also I am using ArcGIS for Desktop Advanced with a school license (verisons 10.3.1 and 10.2.2).
