Plutonium

Just running as admin didn't work, but im chosing this path on the launcher:

just so you know, my game isn't steam, i have downloaded on the last year for free

Every time i open plutonium.exe it asks for my login, and then i try to do the "setup" thing but just doesn't work, it keeps appearing the blue button
OBS: My game was completely normal before and this error started today
Someone help please
