Eclipse Update has broken all GWT Projects?

I just updated eclipse and now all GWT projects are broken.  I inspect the installation and I see everything is installed, the problem is that:

*All my run configurations are gone

*There is no option to run anything as Web Application.

*Error log includes:  
  -Unable to restore perspective: Workspace - Java.
  -Problems occurred when invoking code from plug-in: "org.eclipse.ui.workbench".

*Errors in build path:
[Persisted Container]
gwt-user.jar (missing)
gwt-dev.jar (missing)

Can anyone offer a suggestion what I might do to fix this? 

What is a persisted container?

Is there a roll-back mechanism in Eclipse?
