Downloading the advanced maps not working

Hi all, it’s Giglu here. Maybe someone could help me for having a problem on your server? I dont know is it me and my machine or just the server based problem, but i cant download the nonregular maps that are played often. When a new map is choosed, my game starts to download it and finishes with no problem. But then the problem starts; It starts a new download and game gets an error like “Server attemted to start a new download although there was a other download in progress”. I dont know what to do, i’ve searched youtube and other media to solve this, but no help so far.
