Map won't load.

Another problem!

This was a separate world, in which I wanted to play a map with some friends of mine. I followed the tutorial on the menu to a T, and on the tutorial, it would load the world rather quickly, but when I did it, it took awhile. I didn't pay much attention to this, as I do install games quite slowly, but I could just look away for a minute or two, and it'd be "done." Why I put quotation marks is because when I loaded the world, it wasn't the map. I put in the right version, right software, right map, but It didn't load it. I tried many times, and I noticed around 10% through, it would stop trying to load. Sometimes it would stop before, sometimes it got a bit far, but It still stops. Can anybody help me out here?

Hang on, I'm trying it again, I noticed it was on the wrong version, even though I put in the correct version. ._.

Nevermind, It did the same thing.

Checked the coordinates, went to the location... Nothing's there.

This was the whole log, and yes, it's for 1.8.4, which is the version I have set.

Boukeyt1.

That's the problem, It cancels the upload mid way through.

Sorry for not replying, we have sadly dropped both the modded and map server ideas, and I have no further want to try and fix a problem if I don't need to fix it.
