Serious Error that prevents the program from continuing to run

I keep getting the serious error message when I try to start the Secondary Profession quest and when I press the button on the team list to look at Koss' skills. Is this a problem for everybody or just me?

me 2.
no idea why, and its pising me off

Me 3.

Every single time. I've tried the -image command incase it was something not downloaded but it makes no difference. Hope they fix this soon, was looking forward to trying these heros.

I'm getting same stuff

yeah, only just started doing it though as I have already done secondary prof quest and the heros were working correctly earlier.

I had one when i clicked koss's skill thing, and has one earlier, it just went off randomly.

the heros are causing the game to crash/freeze

lose the heros and your fine

Me 4

Whever I try to click on the Button besides the hero in party Selecting

Yup, started noticing this in Command Training. Urgh, ohwell... this is what betas are all about. I've had it crash on me 3 times now before noticing what exactly was going on... Not using heroes until Anet, does a hot fix!

The problem with opening the hero panel appears to have been fixed a short while ago. If you restart and update to the latest build, it should work fine.
