Drag and Drop functionality

New to the community. New to the software (Delfoi Robotics software) so my apologies ahead of time if I’m in the wrong forum. I’ve recently installed & tested the software & so far everything seems to be on par with my colleagues. However, I am unable to use the drag & drop method when trying to import non .vcmx files. No one here has seen this yet. I had previously had the Delfoi Robotics Essentials installed & un-installed that version & installed the Delfoi Robotics Premium version. I’m not sure if something was left behind that is causing the conflict but I seem to be the only one locked out of being able to drag & drop files. Has anyone seen this issue before?
