I have used DS 2016 and since January DS 2017 for over a year and in the last two months, starting shortly after I bought DS 2017, the program crashes whenever I try to open an existing drawing.  I have uninstalled and re-installed numerous times with only occasional, short term success. As of today I cannot get it to stop crashing. 

 Is there any fix other than giving up and switching to AutoCADlite, TurboCAD or other competitor for this problem?
