Unable to locate projects in library after upgrading to fcpx 10.1

After upgrading to fcpx 10.1, I'm unable to locate the projects in the library. The clips are there, but the timeline inicates that all the files are missing. The newly created "projects and events.fcpbundle" does not appear to contain the projects. Attempts to Update Projects and Events and relinking are to no avail. Are the projects "hiding" somewhere?
