Error creating J2EE project WAS 640

Hello,

I downloaded and installed the 640 WAS sneak preview and installed it last week. I am now working on the first J2EE tutorial and I received an error when creating the project - the popup said "Unable to restore: J2EE DC Explorer. Reason: Unable to instantiate view: com.tssap.j2ee.ui.perspective.view.j2ee.j2eeDCview".

Any ideas how to approach this problem?

Thanks,

Scott
