Okay, so I can't even start the thing up.
I've downloaded and set up the latest .NET framework, and I downloaded and set up Mono, and have even used the Mono control panel to start up Chummer5 - you know, 'mono Folder\Chummer5.exe'. And I even placed the Chummer 5.178 folder INSIDE the Mono folder. But it goes straight to 'Chummer has stopped working.' This says to me that somehow I have something in the background - .NET or Mono, I guess - that just ain't set up right. What am I doing wrong, here?
