Color gradient fills defaulting to black in IE

[aconda]

Please view the file posted at: www.enduroink.com . The five boxes under the heading 'Wide Format Printer Models' were designed with a gradient fill top to bottom (dark blue to light blue; dark pink to light pink, etc.) which were selected from within Blue Voda. The colors are not able to be viewed online and are defaulting to black in IE. Can you please let me know your suggestions? I'm using BlueVoda version 12.1; Browser: IE

Thanks in advance for your help.
