"Edit Custom Group" button causes CTD

[Maris]

SInce the launch of Page 3, whenever I try to click the "Edit Custom Group" button in AE, either on a mission or in the enemy groups tab, HC immediately crashes to desktop and gives me a popup to send an error report. I have already sent one, still, I think I should point out the issue here as well.
