Navigation links within gallery don't work after upgrade

Hi,

I’m excited you added an option to purchase images for free with this version. That’s exactly what I needed! Unfortunately, when I upgraded to the new version to test, it seems none of the links on the gallery page work (Photos, Slideshow, Favorites, Pricelist, Shopping Cart, Exit Gallery). Here’s something I’ve noticed that may be helpful. When I create a gallery, the permalink looks like this:

http://jennifermchughphotography.com/galleries/gallery-1187//?$

But when I paste this into the browser, it looks like this:

http://jennifermchughphotography.com/galleries/gallery-1187/?

Then when I click on a link, it looks like this:

http://jennifermchughphotography.com/galleries/gallery-1187/?/shopping-cart

So I tried deleting the “?”, and that got me to the shopping cart. But I don’t know enough to know what this means or how to fix.

Please let me know how to fix.

Thanks,
-Dave
