I tried fixing the PNG and XML file extensions and that didn't work.
So I went to one of the gadgets and double-clicked the .js file and it gave an error:
"Can't find script engine to open script (jscript)"
Fixed!
Open Command Prompt as an Administrator
Code:
regsvr32 %systemroot%\system32\jscript.dll
Log Off / Log On
Gadgets are now functioning properly.
