Raspberry Pi Installation Help?

[gkusiak]

Something just went sideways on me - the add-ons updated Version Check, and my Seren stopped working.
then when I went to do an xbian update check, that gave me error messages at install "unable to remove" a bunch of packages/stuff.
The reboot that it says was required gets me to the blue diamond kodi logo screnn, then all i get is a flashing cursor on a blank background with no prompt.
