Finally Substance in UE4 :)!

Hi . I subscribed yesterday to unreal engine 4 and since I also own both substance designer and painter I wanted to download the plugin as well. Problem is, since I am totally new to the UE4 and I just wanted to study it for now, I already cancelled my subscription and I think is the reason I get a 404 error every time I try to go on the github repository to download the plugin. What can I do now? I do not want to pay 19 euros again since I payed just yesterday… is there some workaround?

Thanks for any help!
