Needing help, keep getting different errors every time I try to log in.

Maybe try to reboot your computer and see if that fixes the issue?
If that does not fix the issue, go to "Config" in the launcher and hit the button for "Reset system settings". This will delete all of your system settings and reset your game (including your hotbars, UI and other setup), but it may fix the problem.
If that doesn't work, deleting the whole game and re-downloading it should fix it, as a common solution many people appear to find is to change the graphics settings, and so a fresh re-install should work.

If that doesn't work, then I'm stumped. It's not a driver or GPU issue per se, but as an extreme measure you might consider downgrading your graphics driver to see if that makes a difference (this assumes you are using the latest driver for your card).
