Issues with the Pulling Amazon

Hi,
I seem to be having issues pulling in amazon products since updating to the latest version of shopper press? I was able to pull in results with the other version. Has anything changed between these versions please? Also I did notice that all the themes that was in the last version was not in this update, so I did add them back in. Would this mess up pulling in amazon results any?
And was it okay to still use the themes from version 7.3.1 with this latest updated version?
I sure hope someone can help me with getting this sorted it is driving me crazy.

thanks

Liz
