When I select the "Package Explorer" tab, I get a vast white space with only the top of my 10 projects showing up, and not on the left side of the pane like it should, but instead on the right side. It's weird. If I click on it, I get a "Problem Occurred" pop box saying "An error has occurred. See error log for more details. Could not initialize class org.container.directory.Logger".

The error message in /.metadata/.log is this:
