I've had an issue for around a day now where I cannot join ANY byond servers for any games. I have tried:
Clearing the cache
Reinstalling byond
An older version of byond

None of my solutions have worked. What happens is that it plays the regular ad, on some attempts the ads cut off. Then I get the "Your game is loading..." Screen as per usual, but after downloading the game files it stays like this and doesn't do anything more. Another attempt re-downloads all of the files again.
