Problem with app after inserting licence key


When I copy licence key to Bootstrapstudio apps shows me the waiting screen with 3 animated dots and nothing happen for a long time (I killed it after few minutes). Removing \AppData\Roaming\bstudio folder didn't help. I have 2 licence keys registered on my email

One is working very well, but my team using it on 3 other computers. When I put it on my current computer there is a right message, then I use it on 3 other machines.

And with second key works as above...

Can you write to us here with your key:

After few a very long minutes there was a message: "An error ocured while validating your license"
