Slendytubbies Guardian Collection won't start

[Guardian117]

try starting up the game straight from the folder (you can find the games folder in your C: drive) and you can boot it up from here, if the error still appears then idk.

Thanks for replying, but I already tried that and the error still appears, even if I try to open it from the folder.

it looks like theres some error with the UnityPlayer.dll(?) if you want, i can try sending you the dll from my own game folder.

Okay, it's worth a try. Thank you very much. The only theory I have is that perhaps, being an Alpha, it doesn't yet work with several devices.

what device are you using btw

My PC runs Windows 8.1, so I don't know if the fact that it's a somewhat old computer has anything to do with it.
