Black Screen on Tencent launch

Since yesterday, I have to Repair Client all the times I open the game. This is happening because when I launch the game, I get the GTArcade screen, and the game doesn't show the Tencent screen. I only get a black screen and the Repair Client on the top - and by clicking it is the only way to access the game (by doing this, I have to download the 4gb package again and again).

I've already tried to uninstall the game, and it worked just for the first time. On the second launch of the game, I got the black screen again on the Tencent screen.

Is there someone with the same problem who can help me?

Thanks in advance!
