Heya Dangerzone! Sorry to hear you're having trouble with the autologin.
Assuming you're not trying to login to an EMU server, my first suggestion would be to log in the toon manually using the normal EQ login method without MQ running. While this may not be necessary, I choose to do it because it gets all the EQ acceptances out of the way for each account and I know that could not be my issue if it loads. While I hate to ask the obvious, did you watch the video in the overview tab above (
https://www.redguides.com/community/resources/mq2autologin.86/)? Pretty good explanation on how to make this work. Assuming so and you're still having trouble, I just helped a few guildies get this fixed up in discord as they were not super computer literate and I'd be happy to try and do the same for you if ya like, just send me a PM so we don't clutter up the forum and we can try there or in discord if you have it!
