Added the RadChart to a webpart and deployed to Sharepoint Foundation.  It was working but all of a sudden i am getting this error.  

Failed to render "Wiki Content" column because of an error in the "Multiple lines of text" field type control.  See details in log.  Exception message: A generic error occurred in GDI+.  Check the folder specified in the TempImagesFolder property of the control.  Current value is "Chart".  The folder should exist and must have been granted write permissions for the ASPNET user

I have confirmed that there is a directory at C:\inetpub\wwwroot\wss\VirtualDirectories\80\Chart

I also manually set the permissions so that "Everyone" has Full Control on the directory.  It is still giving me problems.  Can someone step me through what i need to do/doing wrong....using Sharepoint Foundation running on my Win7 development system..


Many thanks


UPDATE: figured it out.  was missing ~/ in front of the Temp.  :)
