Hey Richard,
The folder I refer to should be on the C: drive inside the Users folder.
So if your username is Richard it would be in the following folder:
C:\Users\Richard\AppData\Local\Stardock\DesktopX\WidgetCache\[widget folder you're having problems with]
If it's not Richard, just change Richard above to whatever your username is.
And zubaz - yep, it was resolved by this but I'm not gone. I have this thread watched so I'm notified whenever a reply is posted in it.
