i emailed Jundroo, and they told me to rename the game folder to Simpleplanes.backup and it worked. Thanks for the help

@Dpilot Hmm, could be. I don't know why a blueprint image would prevent the game from even launching to the menu (unless it's, like, an absurdly large image file or something), but I suppose it's possible. You could try deleting the blueprint image (or replacing it with a different, smaller image with the same name) from C:\Users\[yourUserName]\AppData\LocalLow\Jundroo\SimplePlanes\Blueprints and see if that fixes it.

@HuskyDynamics01 I've verified the game files multiple times and gotten no notification that anything was wrong
The game worked when I first got it on pc, but the issues rose when I tried putting a blueprint in the game, and it froze and then crashed.
Could that be the issue?

@HuskyDynamics01
Good point. I wonder if they could add something (when simple planes two comes) that is like a built in bug reporting thing, (built in on the site) that you don't need posts to use. Of course, that would be more work for the devs again...

@Dpilot Have you tried verifying the game file integrity through Steam (Right-click in library -> Properties -> Installed Files -> Verify integrity of game files)? I'm not super knowledgeable about this end of the troubleshooting spectrum but it's worth a shot; hopefully a dev can weigh in with a better understanding of what's going on.
@TheMouse The Steam forums and Jundroo's own Contact page come to mind as possibilities, but again it was just a suggestion.

@HuskyDynamics01
Tagging for 2 reasons: 1, know how to fix this?
And two, how can we still allow users like this to be here, avoiding bots?
His sp is not working, so he could obviously not post a plane.
