@uveso Thank you so much! I got the mod!

Hi! I recently switched to a new computer, and am getting FAF set up again. Started installing mods through the client, and wanted to install one of my favorites, Total Mayhem (by Burnie). However, it kept failing to install, giving me this error:

Does anyone know what it means, and how I can download and play Total Mayhem? I've tried logging in/out, redownloading the client, etc. and nothing seems to work. Thanks!

I should note that this is the only mod I've been having issues with.
