AlignToPageCenter adn AlignAndDistribute do not work in X7 using Visual Studio

I am upgrading from CorelDraw X5 to X7. I have an external program writen in Vb.Net and Visual Studio 2013. When I change the referance to use X7 form X5 and run the code below the box is created but the box.AlignToPageCenter does not work.
Nothing happens the box does not move. I have tried box.AlignAndDistribute but that throws an Access violation error. I also need to align text to the center of the box but in X7 that does not work either

I understand that I could simply do something like box = CorelApp.ActiveLayer.CreateRectangle2(0 + 0.045, CorelDoc.MasterPage.BottomY + 0.045, (CorelDoc.MasterPage.SizeWidth - 0) - 0.09, CorelDoc.MasterPage.SizeHeight - 0.09)
to place the red box centered on the page but this is a siplified example of what I am doing. The issue is that AlignToPageCenter adn AlignAndDistribute do not work in X7. What is the alternitive to this. I have a sample VS project but I can not find a way to upload it so it can be downloaded at http://www.cwebtechnologies.com/files/CorelDrawTest.zip

Thanks
