bigbuy install

[Frys]

Hi can anyone help me install the bigbuy module 

https://addons.prestashop.com/en/stock-supplier-management/18228-bigbuy-import-sync-orders.html

i have bought this thinking it will work out the box but nope i have been playing around for the past 4 days trying to get it to install i have followed the manual if you can call it that no joy it will download the images for the comany but not the catgorys or products and its all in spanish the errors 

i have tried to contact the maker but not even got a hello i paid over £100 for it from what i can see its full of errors and should not even be in the addons forsale 

any help would be great i dont mind giving access to the backend of the store and FTP i have tried searching the errors but no luck

 

thanks George
