As you have just noticed, nobody helped you with your problem. I had the same thing happen to me a few minutes ago and had to figure out a solution myself. you need to do the following: open AutoCAD, type in opions, go to the Files tab, click on the + next to Support file search path. Look to see if one of the files listed is.....example........ C:\Documents and Settings\user name\Aplication Data\Autodesk\AutoCAD 2006\R16.2\enu\support. that is the file path of your hatch patterns. if it isn't there do this: click on Add, and then enter the entire file path for the location of the support folder containing your acad.pat file, and click OK............good luck.
