CubikUpdater can't open [Solved]

As soon as I start my CubikUpdater, it immediately flashes back, as long as I can open it without the Internet, but I can't connect to the activation serial number, is this because I'm using the mobile network to share to my computer?Who can help me, I think this is a bug.

Judging by our logs you've connected successfully with your details at least once recently. What exactly have you changed?

The type of internet connection doesn't matter, as long as you're connected at all.

Try backing up your C:\Users\<user>\AppData\LocalLow\BDcraft\Cubik folder, deleting the original and trying again.
