On IDE startup I'm receiving "java.lang.IllegalStateException: You cannot use SL[/CompilerType/JavaExternalCompiler in more than one AbstractLookup" exception. I select OK on the error dialog window and the IDE comes up in the last project I had open. When I try to expand any of the "directories" within the project, I receive a "java.lang.IllegalStateException: Duplicate pair in treePair1: SL [/CompilerType/JavaExternalCompiler" exception. The only way to get the IDE to work is to switch to another project. I get the same "java.lang.IllegalStateException: Duplicate pair in treePair1: SL [/CompilerType/JavaExternalCompiler" exception, but the IDE is functional at that point. Then I switch back to my original project, get the exception dialog and I'm good to go.

Probably java related, reassigning.
Does not look like a java module problem to me. Maybe corrupted user settings? Openide guys, please help.
