I seem to be having trouble starting CoH on my Mac. I played yesterday for a couple hours and all was fine. After the update today (4/28), when I click Next and I Agree from the updater, rather than getting the blue LOADING logo like I normally do and going to the main CoH screen, my screen simply goes black and stays that way. I get no music and no main screen. Is this a known issue, or perhaps something someone else has had a problem with? Any help would be greatly appreciated.
