Minishop2 help

Hey all, having a problem with minishop that I am hoping you guys/gals can help me with.

my category page is here

http://jbmautomation.com/onlinestore/speaker-packages/

but when you click the product link you get this

http://jbmautomation.com/onlinestore/speaker-packages/onlinestore/speaker-packages/speaker-package-1.html

instead of this

http://jbmautomation.com/onlinestore/speaker-packages/speaker-package-1.html

why would it double up the

onlinestore/speaker-packages

thanks in advance for all your help

I followed this tutorial to get it set up:
