HELP! IT JUST GO WORST I JUST LOST MY ENTIRE SHOW
Guess you're on one of the latest versions. They are really buggy and the best way for you is downgrade to any stable version. For me it is BETA 25.10.14.5, thinking it will work good for you too. GL.
Where do I can download?
Just from the updates tab in the settings.
Mind it that you must choose BETA source as it didn't get to the production somewhy.

Also, if you're using Windows, then to downgrade your EMU you will have to install this version twice. For the second time use "Repair" button.
If you're using Mac. Then you must delete your current EMU version. And then install this one. No worries, your settings, shows, license (if you have it) will stay.
Debekup
I'm trying to work with the EMU program, but it keeps freezing, and I have to uninstall it from my Mac for it to work. This makes me lose my entire lighting setup over and over again, as it's the only way I can get it to open again.
