When I start ACE, I get a box with a red X to come up.  ACE will start, but I am unable to add any new liveries to my 757.  I have the correct files in the variant folder, but they do not show up.  I am using an Intel I7 processor with 8GB ram, 1024mb video card, 1.25TB available space Windows 7 OS.  Any help is appreciated in advance.
