I've been having this issue for a while, and I have the game installed on 2 computers (one at work and one at home.) both diff't hardware builds, but same software loadout. Work computer has been suffering this issue since I formated it not long ago (4 weeks) Now, my home rig is doing the same thing. Launcher loads, doesn't remember me at all (Normally has my user name filled out) I fill in the blanks, and hit login, and the launcher crashes.
I am having the a similar problem. THe game starts to load and it gets past the Cryptic loading screen into the games loading screen and then crashes.
As far as I know I don't have teamview installed on my pc.
You can load the Launcher, get to loading screen and when it starts to load Character selection view you crash? If that's the case, there are some people who have fixed it. A quick search should reveal those topics. Else you can try and verify the game files.
In launcher click ''Options'' top right corner.
Then mark the ''Force verify'' option.
Log in and let it verify the files. Can take some time, so be patient.
Have you tried to use the ''Get the latest launcher'' topic? Could be that it would fix that.
