Can no longer launch apps after upgrding to android sdk tools 20/platform sdk tools 12

Question

I upgraded my sdk tools and now I can no longer launch apps from Eclipse (I can still install from command line. When I launch I get an error window and an empty device picker. Error window says:

An error has occurred. See error log for more details.
com.android.ddmlib.IDevice.getName()Ljava/lang/String;

I'm not sure what log to look for.

DDMS sees the device ok as well. I'm not sure whats wrong here and can't find anything on google or SO.

Thanks

Uninstalling and then reinstalling the tools solved the issue.
