Tanki X Stuck on updating

I am sorry this is not a Tanki Online topic, but I can't find answers to my problem anywhere so this is my only choice.

I downloaded the launcher of Tanki X, and even if I don't have a key yet, I still keep updating it, without playing, however from some time when i open the launcher it starts updating and gets stuck at the end, with nothing happening afterwards....I tried uninstalling and installing again but it won't work, help????
