APP Crashing after Login button Pressed

Has anyone had the error shown below? This happens when I run the downloaded app with no changes. I am running the ADT on an imac.

I fixed this error by reinstalling the ADT bundle and Eclipse. Now focusing on making slight customizations.

Through this problem I have discovered that Xcode is a much better IDE than ADT. The android build breaks when you try and rename it. That step alone is a process.

Thanks for the responses.
