Good morning community

I have recently had my laptop changed from XP to windows7

I have AutoCAD 2002 on my desktop which I use during the day - still running XP - windows 7 desktop on way

I have loaded DraftSight onto my laptop - 64bit

When I open a drawing from my previous work  a pop up box appears -

Shape file - LTypeShp.shx

If I hit browse programme crashes

At the bottom of the Shape file box is a message-

Specify shape file for genltshp.shx - shape file not found

Can anyone advise action

Thanks in anticipation
