Going here - https://secure.ptc.com/Saba/Web/,DanaInfo=www.ptc.com+ptcu , logging in, clicking launch now on a current enrollment (Detailing with Pro/Engineer Wildfire 4.0 to be specific) causes a window to appear with a selection of modules and lessons. Many of these lessons are broken and load a blank page. I have upgraded Java and Flash and IE all without prevail. What could be some problems that are causing this?
