Help with World Upload

Sorry for my English. Im not american.

Hello! I wanna play some survival maps with my friend, but I upload the world, and it says "Fatal Error on Uploading: NoUpload". I already checked everything, its on ZIP, and, here is the link of the map:

http://www.minecraftworldmap.c…VsVuO#/-161/64/423/-5/0/0

I checked everything that is on the FAQ :3 And every map that im trying to upload gives that error... Help!

~Thanks!

Yeah, I checked it. I don't know if this map is bigger than 50 MB, but the others I tried was. Gonna try again.
