XML processing error when opening .mmp files
When I attempt to open .mmp files whether from linked map branches or by double-clicking on them in Windopws Explorer, MindManager throws an XML processing error saying ...
0xC00CEE2D, Unspecified error
It used to open them well and allowed me to convert them to .mmap files but now I can't even convert them so as to open them in the new file format.
I'm running MindManager version 21.1.231 64-bit on 64-bit Windows 10 Pro. And the problem arises on a second PC so I'm not sure that the probl;em is my operating environment.
Might anyone know how I get MindManager to open .mmp files again, perhaps? Many thanks for your help.
