Have been attempting a successful download of DraftSight V1R5.0 (beta) for Mac for over 2 weeks.  Using 2013 iMac with 64-bit processor.  Have deleted old DraftSight versions from Applications, Library, etc.  New version downloads, but never prompts me to enter E-mail Address for Activation of product.  Also, upon opening the V1R5.0 DraftSight I just downloaded, get the black workspace, properties, but no top menu bar & tool matrix is blank.  Please advise!  Unable, obviously, to use this product which I rely heavily on for CAD.
