When I double click on a DWG file on my desktop or my documents, Draftsight opens but then I have an empty document NONAME_0.dwg and it reads the following error messages:???

Unrecognized command /Users/christophebeguel/Desktop/01-10-20. Press F1 for help.ROG

Unrecognized command PAR. Press F1 for help.ARG

Unrecognized command DFA. Press F1 for help.Dulles

Unrecognized command Dulles. Press F1 for help.Survey.dwg

Where Dulles is part of my file name (complete file name: ??01-10-20 ROG ARG Dulles Survey)

Quite annoying! I can only open the files through FILE \\ OPEN. This happens on all files I try to open by double clicking on them.
