Collectible Card Game Headquarters

Hi!

I just downloaded the launcher and here's my problem:

I can't download the images. When I click on "images", a little window appears, saying "check which card images are missing..." and that's it. I waited for more than 30 minutes now and nothing ever happened.
Is there anything I can do about?

This happened to a friend of mine aswell. Is this a known bug?

This is happening to me as well. Can someone please explain how to fix this as simply as possible? Would be great
