I noticed an issue with that as well, when trying to run the WeatherClock widget under DesktopX 3.
The Oxidized suite came out while DesktopX 2.x was current, so there may be some issue with running the widgets under DX3.
I found that running the WeatherClock "object" (instead of the widget) worked just fine, though DesktopX has to be loaded.
If no one else replies here with a fix, you may want to contact tech support at support@stardock.com to see if they know of a fix.
