Game Booster failing to add games

I have been using Razer Cortex for the past couple months, and it's worked fine for most of that time. However, I've started buying games every couple of weeks and the past couple of times I've tried to add games, it wouldn't add them. Last time, it added the game, Blood: Fresh Supply, after about a day. I figured it was probably because it had just come out or something and went about the rest of my day like normal. I decided to buy some games last night, namely Deus Ex: Mankind Divided and Quake, and it's been refusing to add them both yesterday and today. I have also repeatedly tried to add the games manually, but every time I do, it says that it failed to add the game. Is there any way for me to get this to work or do I just have to wait for it to suddenly start working?
