Older version expired yesterday so downloaded Draftsight 2015.  What a disaster !  The files I have been working on recently would not open.  Had to get an Autocad user to Audit and correct the files.  This has recovered the files I know about but I hope there are not more that can not be opened !  Any ideas on this ?

Also, there are many entities that no longer display correctly.  They appear only if the cursor is passed over them.  Any ideas on this, would be most grateful...
