I got your report.
It seems the Mods haven't been deleted, but the ModIO plugin doesn't report them either.

You don't have hundreds of recordings in the Recording menu, right ?
I designed it so if there's no Mod reported, nothing is deleted... If you confirm me you don't have recordings, then you'll have to manually delete the Mod drive (it'll delete any recordings you may have as well) :
To do so :
- press the menu button on Tennis Elbow 4 in your Xbox game library
- select "Manage game and add-ons"
- select Saved Data
- Select "Reserved space" and clear it
Launch the game and hopefully, you'll be back to a viable state...
