Well, I have no Ace license for you but there are a few things you can do.
Make a proper steam setup so that it doesn't show ads. (Steam / Settings / Interface / - Notify me about additions or changes...)
The next thing you want to do is to create a base_project to avoid having to use the new project thing in Ace.
1. Create a new project in Ace (remember your project folder inside your windows file system)
2. Go to File / Manage Project and delete your project from steam cloud (just from the cloud!!!)
3. Close RPG-Maker... done.
From now on, whenever you want to create a new project, just make a copy of your base_project and rename it.
To edit your project, just open the old or newly created project folder and double click Game.rvproj2 inside it.
My workstation is off-line most of the time and steam allows that ace is launched off-line. Just don't touch the Manage Project Button beside the Playtest button or File / Manage Project entry or Ace will freeze while trying to contact steam. There is a timeout but it takes several minutes for it to trigger.
And btw. there is a lot of Community Content you can only access with the steam version of Ace.
