So last Thursday, I log on to Autodesk 360 for the first time, and sync to the cloud. No problems all day.
Friday morning, I started AE, open the project and drawing I was working on the day before, go to icon menu to insert a Icon from the One LIne Components category, and I get an AutoCAD Message "File not found: HDS11_1-.dwg", showing that the icon is not found in any of the search paths, including C:\Users\Public\Public Documents\Autodesk\Acade 2013\Libs\NFPA
However, when I search my computer for HDS11_1-.dwg, the file is there in C:\Users\Public\Public Documents\Autodesk\Acade 2013\Libs\NFPA. In fact, there are several versions of this file, all of which are found in a named search path.
This is still a problem today, so restarting the computer had no effect. I logged off Autodesk 360, and restarted AE, also with no change. The problem only appears to be with the One LIne Components. I did not have this problem before signing into Autodesk 360. Maybe it's a coincidence...
What the heck happened, and how do I fix it? Any ideas? Suggestions?
