New, but with issues

[CorvaVespera]

So, last night I finally downloaded and installed Discovery Freelancer, however I've got a few technical issues that need resolving. For reference, I'm running Windows 10, 64-bit.

1. I can't save my games, at least not permanently. Whenever I exit the game and come back, any saves I made are no longer there.
2. I can't change the resolution to widescreen, and I don't have any of the antivirus softwhere listed here. The game still runs, I just can't change it to widescreen.
3. I can no longer play vanilla Freelancer - after the intro movie it just changes to windowed with a black screen for a few seconds, then exits.

Not a fun set of issues to have together. Any suggestions? Any additional info I should provide?
