invalid partner properties signature! ayuda como puedo solucionar eso?

Hello, Is there a way to change the size of the window? It's super tiny on my ultrawide monitor. I'd found the file that holds this info but if I make any changes then the game won't even start anymore due to partner signature being wrong. Thanks in advance....

I loaded up an old save file and all the fish in that single file have the dead sprite and the backround is an odd space? I am scared... What happened?

This was one of my favorite games forever! And I just added it to my steam library. BUT it won't open. The icon goes to my task bar, but nothing shows up on the screen. I have Windows 11. Is there a settings conflict? I can't even get to the setting menu to makes changes. It simply will not open....

Failed to initialize DirectDraw: RESULT_SURFACE_FAIL CreateSurface Windowed Primary: DDERR_NOEXCLUSIVEMODE can someone help with this error?
