30 day trial DS professional is over, but DS professional menu is still there.

The 30 day DS professional period has passed and when I open up DS, I am asked if I want purchase, so I say NO. The program opens up fine, BUT the DS professional "menu" is still there. It's been about 20 days since the 30 day trial is past. How do I get just the free stand alone only to use. Yes, I did read all the blogs on activation process. Never got to the point to activate !! Need a new answer to this problem. After almost 3 weeks, still getting that dialog box asking if I want purchase Profession ver of DS ?

Sam
