The new ebay module by Prestashop... but still, doesn't work?

[Rain_xx]

Hello.. I just tried the new 1.5.2 prestashop version, and downloaded the new free ebay module:

http://addons.prestashop.com/it/modules-prestashop/2742-eba.html

 

This doesn't mean to be just for France, it says that it has a full compatibility.

But, when I just upload the folder to 'modules', the back office module page stops working.

 

...there is a simple solution for that?

 

Thanks for paying attention.
