Marketpress – global marketplace products redirect to non existing product

I’ve just moved to a new server, upgraded to 3.1 and latest Marketpress plugin.

I cant seem to access products from my global marketplace anymore and the image seem to have disappeared.

Here is my global marketplace:

Then, when I click on a category, I get a list like this one for example:

When I click on the product though, /marketplace/ changes to /store/ like here

with this standard error message:

Sorry, we can’t find the content you’re looking for at this URL. Please try selecting a menu item from above or to the side of this message to get where you’d like to go.

Any idea whats causing that? thanks.
