Can't play videos. Its buffering like 1997

I need to get a promo video but I can’t see the videos because it buffers like I haven’t seen since 1997. It plays for one second then buffers for 5 seconds. And before you say it, my internet is alright.

I checked it last night and thought it might be a temporary issue but today again its the same result. Its apparently a problem at Envato’s servers. The same thing happens at Elements too.
