Problems Printing PDF’s Created from Stacked Viewports

Ok guys, don’t know if anyone else has experienced this issue but I’m having troubles printing PDF’s created from Layout from sheets with stacked viewports created with ConDocs. I’ve had this issue in the past and it’s always been a raster image outside of my sheet area that causes the problem. This time there are no viewports outside the sheet edge/limits. When adobe starts to flatten the progress bar just hangs around 50% or it completes the flatten process and then gives me an error that it can’t print. I need some help on this one as this is my first complete project out of ConDocs and I can’t print it
