I updated my IntellIJ install to the latest version (11.1.4) and now the Editor window doesn't appear. Double-clicking on the file, jump-to-source, nothing happens. No error message, it just doesn't appear. If I double-click on an xml layout file the preview window works, but no Editor window. Have installed and reinstalled; went back to an earlier version and it doesn't work there either. I'm at a loss. Any ideas?

Update: Editor works if I create a new project. Update 2: idea.log file includes this (I don't know what ins.android.sdk.AndroidSdkData is):
