Problems with dialog boxes, menus and commands

I just downloaded and installed free DraftSight 2015, but I have a problem with missing dialog boxes.

None of the commands like New, Open, Save will open any dialog boxes.

I have used the command "dispalydialogs" and set that to yes, but still no luck.

I have also uninstalled it, removed the folders under Appdata/Roaming... and under Program Files, installed it again, but still no dialog boxes.

Any ideas?

 

Thanks
