John, to keep you up to date, I'm also sending hereby my reply to MindJet, without the attachments, because they are not in the list of file extensions.
"Thank you, Diane for your reply.
I am currently using MindManager Pro7 v. 7.2.374 (6/10/2008). I believe that I received your e-mail announcing the update to this version on 6/13/2008, and decided to download the earlier version to the Parallels environment, to use my activation code for it (with no problems) and then update to this last version, with the new activation key that you sent me.
Some of the maps in MyMaps folder were created with Pro6, many with Pro7 (various versions). I will attach a map created sometime between January and March 2007 (I don't know how to look up the version or build of the MM that created it).
I have tried to open those files from the "Documents" folder on my Mac hard drive, as well as the "My Documents" > MyMaps folder. In each case, the map appears briefly on the MM desktop, then the "error warning" which closes MM. (Mindjet MindManager Pro 7 has encountered a problem and needs to close. We are sorry for the inconvenience.)
For your info, I had stored all my files, docs, pictures and music on a Maxtor OneTouch II external drive on the PC. I backed up all the files, formatted the external drive by the Mac, copied the files to the Maxtor, then copied all files from the Maxtor to the Mac hard drive. I believe I installed Parallels before transferring all files. All my photos and music files work fine, all my Windows Office XP files work well in their Mac counterparts. The files and folders showing on the Mac and in Parallels seem identical.
But in addition to not being able to open older files, today I can create a small file, I can save it, but I cannot open it again: I get the "error warning" that closes MM. I'm attaching that file.
Hope this is helpful. Let me know if you need more files to view.
Ronny"
