[Did the XBMC4gamers update and it gave me an error / now stuck on XBMC Fatal error]

Hi all,  I've been googling and searching and not finding an answer to this. 

I fired up my Xbox today (first time in a while) and got a notification that a new version was available.  I went into the settings, updated the URL downloader and then did the XBMC4Gamers update.

After a bit, I got a message that "autoexec.py" or something like that failed.  Now I'm stuck at a screen that says XBMC Fatal Error: No suitable skin version found (see screenshot)

I am able to FTP into the xbox just fine.  I did find some mention of a guisettings.xml file but I can't seem to find where it might be and where I can get a replacement for it (if that's even the problem)  My default dash is/was xbmc4gamers, BTW.

I would appreciate any help!
