About a month after the release of Vectorworks 2015, Nemetschek Vectorworks, Inc. issues Service Pack 1. The update covers the following fixes:

Fixes problems when rendering viewports in OpenGL, opening Mac files that contain special characters such as / or : as part of the file name or file path, and displaying a black screen when creating animations. We also corrected multiple issues with exporting to image files, centering the drawing on internal origin, and using the Publish command, as well as problems running Vectorworks 2015 in Windows XP 64-bit.
