Has anyone ever seen the "Error:Failed to Save Data" message in DMC3?

I haven't found anything abot this error at all. I've tried almost everything I can think of to fix this problem, including messing around with admin privileges and compatibility settings, firewall and antivirus exceptions, reinstalling, and verifying game files. Interestingly, this was not a problem with the other 2 games. DMC3 simply won't save. It doesn't crash or anything, and the message isn't a popup. The game gives me the error before going back to the previous menu. Does anyone have any idea how to fix this?

Gonna comment this on a couple of threads that I went through in trying to fix this crap. It fixed it for me, at least for the moment.

The behavior above was the same for me, the DMC1/DMC2 saved alright for me too but DMC3 refused to work. Tried everything above including moving the game and Steam to different drives, removing dmc3.sav and all that good stuff. Uninstalling and re-installing it helped for a little moment but the problem returned soon after, maybe after a few levels.

What's been working at least after completing a few missions and between game restarts:
-Navigate to $Steam_installation_directory\userdata\$your_user_id\631510\
-- Usually Steam is in C:\Program Files (x86) or whatever
-Exit Steam (I did this once without this step and it didn't work without it)
-Remove remotecache.vdf (or back it up in case you're worried)
-Hop back into Steam, it should generate automatically
-Launch DMC3HD and try to save again

I had a look at the removecache.vdf that I had before removing it, it had some random options - Copy.sav file detailed which I assume was from when I took a backup of the options file before changing resolution options there. My only real assumption at this point is that some kind of mismatch between the files present and the vdf-file which caused saving to go ♥♥♥♥♥♥♥.

Hopefully this keeps working and helps someone.
