Delete Game Save Data ... AGAIN!!!

I’m having the exact same problem like I had in FM7.

I have to delete my local save game, because something went wrong.
Already had it 3 times in 2 days, but today I got a little extra trouble:

First I got an error E105, then an error E102. According to the Xbox help page I had to reset my console to the factory settings and install the game (all my games) again.
Since nothing else worked (hard reboot) I reluctantly tried this option.

Now it’s trying to install the game, but the installation stops (giving my a notice) and when I try to resume, I get another error.

Is anybody having similar problems and does anybody know a solution?
