The mods won't go away! I have deselected them all and hit the patch button, but it still runs them. I even removed them from slipstream. Still nothing. I would really like to get the vanilla version back.

Whenever I try to patch mods I get this message:
Patching failed: java.io
FileNotFoundExceptio: .\backup\data.dat.bak
What do I do?

And if you have any mods still active, also verify FTL cache (reinstall if non - steam) before you first launch the new mod manager.
