I've tried uninstalling and updating to the newest version. Everything I've tried keeps giving me this error.

Hi there, and welcome to NRaas.

Not sure if we are seeing enough of the error in that display box to tell, our developer or one of the others may have to comment, but in case this is a .NET failure do you have .NET 4 installed and activated?

Also, as I am sure you know but just stating the obvious, it's not required to use the Mod Updater. Players can always update their own mods or just replace them with current versions if they aren't sure of what they already have (although most script logs will report all of the NRaas version numbers, as will Overwatch through its Version command).

Hmm, how did you obtain this install of the game? Is it origin, disk or something else?
