All it has done is updated your xbox dash, presumably you had evox installed and that inturn was named Xboxdash.xbe.
Get yourself to XBINS IRC and dload a boot disk and a dash, once you have one of those you will be able to rebuild your dash back to evox.
Put your boot disk in the box and set up the NETWORK part with the details you need to connect to your PC, IP, DNS etc etc.
FTP into the box to the root of C, rename xboxdash.xbe to xboxdashorig.xbe,
Your evox dash should contain the following:
evox.ini
evoxdash.xbe
Trainers
Skin
Edit the evox ini file to the correct settings, IP folders etc, rename the evoxdash.xbe to xboxdash.xbe and FTP them all over to your C drive.
Or just use an auto installer.
