Launcher closes as its logging in. Any advice?

[Squizard]

Every time I open the launcher it will get to the logging in part of its set up then close. I have reinstalled the launcher a couple of times now. Any advice?

if you're using steam, make sure you are signed in and are in online mode, then try Running the launcher as Admin.

make sure you are on version 1.5.8
