Hey, sorry you're having so much trouble getting your games working. I'm not the most tech-savvy person, but I'm familiar enough with the launcher that I can give you a few suggestions regarding what the problem might be, based on your screenshots.
Basically, what you're seeing is something we call the wrapper. The fact that it is showing up with missing art and other assets indicates to me that it's having trouble connecting to our servers. If you have any firewalls in place or any particularly picky security software, you may want to try temporarily disabling it and see if that helps.
Alternatively, do you happen to be trying to connect through a school server? Those have caused similar issues in the past (again, due to the security software in place).
Let me know if any of that helps.
