You can bypass the 2002 error by right clicking on the launcher (if you're using a PC) and select "run as administrator". That will get you to have the start button lit up and able to click to get to a character list. BUT what it will do is then bring you (most likely) to the wonderful 1017 error.
Last night I had hope it was fixed and working as I was finally able to get onto Midgardsormr since the first day of Pre-launch but then today, after that small little patch from SE, it's back to being jacked up again.
