I have a bug in D.A. 1.6 . It had worked flawlessly until I updated my Nvidia driver for my 7800GTX card as Cari Elf had recommended. I have tried to drag and drop debug.err file to this post unsuccessfully you should have an attachment link but you don't. I het a memory dump which points to nv_4display.dll. I had this problem in the past. Since Stardock had fixed this when D.A. came out. I don't know why your code conflicted with the new Nvidia driver, which Cari Elf said would address my long-standing issue.
