Problem with creating list box or other controls

I have created numerous worksheets with list boxes controls in MathCAD 13. Now, when trying to open those worksheets in MathCAD 14 the list boxes do not work and a message "Value cannot be null. Parameter name: pUnk". Same thing happens when reviewing examples from Quicksheets or other downloaded example worksheets from the internet. I do not seem to recall that I was ever able to open and execute a list box after upgrading to MathCAD 14. Also, when trying to Insert -- Control -- List Box (or any other control) ... nothing happens. Any idea on how to make the list boxes (and the other controls) work again? Thanks for your help

Hi Peter,

Maybe this tip will help you: http://communities.ptc.com/message/199124#199124

... find mcmreg.exe (C:\Program Files\Mathcad\Mathcad 15), start it and navigate to the *.mcm files in the C:\Program Files\Mathcad\Mathcad 15 folder and register them that way...
