I am very new to MindManager 2020.
I cannot open my .mmap file containing all of my work. When I attempt to open the file I am greeted with an error that says "Invalid file format, directory record is not found. and then Document file (Document.xml) not found in archive."
Can someone please tell me how to recover my work?
My map is at
Any help is appreciated.
Thank you.
