Went to login to the console this morning and got few errors about bad 
PNG files.  Logged out, now I can't log back in.  The lone dialog box 
has the following:

There was an error loading the theme Default
Couldn't recognize the image file format for file 

I click OK, nothing happens.

Suggestions anyone?  Thanks!
