What message does it show? It should be telling you the reason why.
Also, you don't need to upload the map, a screen-capture should be just fine.
no i wanted to create a map and upload to public it says i need a uploader name even tho i filled in my email, name and map name can you please help me?
That's weird, maybe it's a bug. I'll look into it as soon as possible.
Hey Seragamer, I haven't been able to find any problems with the uploader. Is the upload still not working for you?
so I just tried it and now it works I don't know what happened.
That's relieving to know, thanks!
