I had the same problem. Google it some more. I had to delete a specific folder and reinstall the launcher from scratch and then it worked. There were a few other steps tried such as opening it in safe mode or network mode and trying it there.
"Jawa's Paradise"
"Stop or my jawa will shoot"
"Jawa man"
"Evil Jawa"

I was a beta tester for the last weekend before launch and have been a subscriber ever since. I have found it is worth the benefits of being a subscriber. I just hope they start to offer up more gear to maybe a subscriber vendor and update that as much as they are updating the CM. Still having a blast with the game and I play when I have time. I have 1 toon leveled to 50 and 3 others ranging from 1 to 43. I don't use the toon too much after 50 cause of lack of time and leveling the other characters. I hope bioware can keep up the good work but just add a little extra for the subscribers.
KOTOR 1 and KOTOR 2 are a little different from this game. Try upgrading the armor and weapons of each character and that may help. This is my first MMO and it takes a little getting use to. Also depending on the boss you're fighting try changing up strategies. Few questions.....Did you upgrade your Jedi powers? upgrade weapons or armor? what else have you tried?
I try to get in a variety of games. COD, Halo (many versions), kotor 1&2, Battlefront 1&2, whild I am also starting up mass effect so I can catch up with the story and play all 3 of them.
