Launcher MB2 Launcher stopped working

[*Rhiannon*]

Hey, I'm experiencing some trouble with the MB2 launcher. Basically when I try to start the launcher it just gives me the "MB2 Launcher has stopped working" and the options to look for a solution online or close it. Now I've tried reinstalling the game and deleting all the files I could find that belong to MB2 (I don't know if that counts as uninstalling but for some reason it wouldn't come up in the "Uninstall or change program menu", so I'm not sure if the uninstall was properly done). Also deleted all the files in "C:\Users\[USERNAME]\AppData\Local\Movie_Battles_Team.
Tbh I don't know what else to do. pls halp

This is what comes up when i click "View details":

In other words. Puppy has FAILED you!

Pupps, You have failed These Forums!

Maybe I did, but honestly I'm running out of ideas over here.

The only thing I can suppose is that viruses still aren't removed completely -- some of them weren't detected by anti-virus.
*Rhiannon* didn't mention what AV he's using and have he tried some another software.
So purging all data and reinstalling Windows may work.
