I'm using windows 10, Microsoft Edge.
So I uninstalled the stable version of BYOND completely, and installed the BETA Version of BYOND, I installed it into my program files (automatically selected). Then I was going to play Colonial Marines on space station 13, I launched BYOND as an administrator and launched the game.
I expected the game to launch fine, the BYOND launcher was working fine, I could access everything normally, so I went to launch Colonial Marines, and when I got in I got multiple messages saying "Unable to open cache file.". and the screen was black.
I talked to an admin and he told me to clear my cache, so I cleared my cache, launched as administrator and tried again, I had the same problem, So the admin recommended I install BYOND Beta somewhere else, So I installed it in my downloads folder, launched as administrator, launched Colonial Marines, and still, I had the same problem.
I don't know if anyone else is experiencing the same problem as me, No one else has mentioned anything about it. So please, if you can help, or provide a different option to use BYOND Beta, please let me know as soon as possible.
