I'm sorry. If you are still having problems, can I ask you to consider going to the official forum and posting about your problem here: [URL="http://forums.rpgmakerweb.com/index.php?/forum/4-rpg-maker-vx-ace/%C2%A0You"]http://forums.rpgmakerweb.com/index.php?/forum/4-rpg-maker-vx-ace/ You[/URL] will not be spammed - this is a very responsible forum and is the official U.S. forum representing ACE. They have very good staff and I will watch out for your topic there. I know the staff there and they are very knowledgeable. Please tell them that you have already created a new project and copied the Game.rvproj2 file from it into your current project.Since that didn't work, you copied your Audio, Data and Graphics folder into the new project and still it doesn't work. And the message you are getting is "Unexpected File Format" I am sure that they can help you beyond what I know. I will be watching for your post.
