Hi!
Since yesterday I have created a class diagramm.Today I wanted to make a relation beween two classes and suddenly nothing on the drawing desktop worked anymore. I could not move the classes or make new ones. So I have closed the file and wanted to reopen it. But now all information of the classes are away and I get the error in the title and short time later a java null pointer exception. What can I do, I tried to open a file from the local history, but then I get the following error message:
error no label provider for org.eclipse.uml2.diagramm.clazz.navigator.UMLNavig

What can I do, this was a lot of work and I do not want to make it again! I have put the error log on my website: http://www.nettania.at/error.log

Greetings,
Florian
