Realms Update Limit Failure ERROR 6004

I downloaded the latest copy of my realm world before uploading a singleplayer map to show my buds. After three or four uploadings of different singleplayer worlds, I decided to re-upload the original that I had previously backed up by "downloading latest". I received the error code 6004 and am unable to upload my original map. I am now stuck with the current world. Realm ressetting did not work.
