With cathedral window quilts, the curves around the sort-of-square shapes go along SW-to-NE and NW-to-SE lines, not North-to-South and East-to-West lines. Your EQ7 layout does the latter, which means all your blocks would need to be rotated 45 degrees.
I took your layout and rotated it 45 degrees and drew a few squares of where the block edges are. If you can do the rotation in EQ7 (I just used paint), that should help you figure out the layout.
