I keep my project on an external hardrive. When I had to quickly eject the hard drive, I didn't bother to click "Safely remove hardware". I
think I had closed the Game.rxproj, though I'm not entirely sure, and I know I had the project folder up when the flash drive was ejected. Now opening up the Game.rxproj gives me a 'Failed to load system data' error. Opening the Game.exe gives me the popup:
Script 'Scene_Title' line 29: ArgumentError occured.
marshal data too short
And then the game window closes. I tried copying over the scripts.rxdata to a new project, which worked, but copying the entire Data folder and attempting to open the rxproj gave me the same error. Thankfully, Audio and Graphics are definately safe, because I used a different RTP to hold their data.
Please, if anyone knows how I can recover the data, I'd be grateful. And of course I'd update this post if insufficient information was given.
