Nuendo/Cubase Softube Flow mastering suite issue

Hello Everybody…Has anyone used the Softube Flow Mastering Suite inside Nuendo/Cubase? I have successfully loaded the program…have it appear in my stereo out buss BUT the right side of the Flow screen is chopped by a few inches. I cannot widen the screen or or re size it in anyway. The chopped portion missing shows the right output portion of their program . Please post if anyone has had the same issue and the fix if you can. I am still able to use it but frustrated that I am doing this " subscription" and do not have the full screen/ capabilities. Thanks everyone.
