When you want to activate the license and nothinh happens when you click "Continue" button or you get "Cannot connect to server" error message, you need to edit your hosts file.
Windows 8 or 8.1 or 10
Unfortunately Windows 8 or 10 makes it annoying to open apps as administrator — but it’s not too difficult. Just search for Notepad, then right-click on Notepad in the search results list, and choose to run it as administrator. If you’re using Windows 10 this will be on the Start Menu.
If you’re using Windows 10, it’ll look more like this:
Once you’ve done so, open up the following file using the File -> Open feature.
- Find any magicalmailapp.com entry in his hosts file and remove it
- Then try to start Mailbird and input the license again
That should do the trick. If you need any help with this, please send an email to firstname.lastname@example.org.
