I downloaded the new ST6, but unfortunately every time Click ANSI Part to develop a new part only the tool bar show up. There is gray screen, and I can still see the default page consisting up ANSI Part, ANSI Sheet Metal, ANSI Assembly, etc. This problem occurred last time when I downloaded ST5, the solution was easy and short, but unfortunately I forgot how to fix it. I took a screenshot to help demonstrate my problem. What do I need to do? I really appreciate your help.
