The mixer works for a couple of seconds, then a licensekey type of code shows up and says it's offline. Then everything locks up. I think it cant find a network. Tried turning of firewall and windows defender, but same thing occurs. Grateful for any help given.
This could be a variety of different things. The first thing to check is to see if the engine is staying up, or if that is what is turning off. If you send in a ticket my colleagues on the support portal will be able to help you get to the bottom of it and find a solution. If you could send in your logs (Zip Debug feature in the Advanced Tab of HippoLauncher will gather them for you) and the version etc you are running that would be great.
