Good day.
I was working in the studio when it said, that some error happend, please restart. OK, I closed studio, then opened it, but...
When I load it - it says "Problems occurred restoring workbench.
Unable to restore perspective: Workspace - Resource."
Then "Internal error has occured":
Plugin name: Metamodel Core
Plugin ID: com.sap.ide.metamodel.core
Class: com.sap.ide.metamodel.core.plugin.MetamodelManager
Method: getJavaProjectClassPaths
Message: project has no Java Nature. projectName = LocalDevelopmentxxxxxx.com
Exception: org.eclipse.core.internal.resources.ResourceException: Missing project nature class for org.eclipse.jdt.core.javanature.
That message appeared with an every attempt to load every project.
When I try to create a new Dynpro project it gives an exception also...
What happend? Have I to reinstall the studio?
