Help with trainer for Farcry 4

I downloaded the +8 Farcry 4 trainer, but it doesn`t work.
I pressed dpad up + back and it didn`t open.

I did notice I`m on TU7 (PAL).
Could that be why?

Please move this thread instead of deleting it if wrong section.

 

Anyone?
Any help is appreciated.

 

you need to check youre title id and media id if not the same it wont work and if it is for a specific tu then you must be on that aswell
