I have the same problem and this solution does not work for me.
Our MII 12.2 SP7 does not give any option to synchronize when right clicking project.
However, Tools => Sync file to Tree is there.
It does run without any output on all but the catalog tab.
But with Catalog tab the "Sync file to Tree" results in the following Error pop up box:
" 2
[OK]"
Whatever that means, it doesn't help the corrupted export tree, 98% of our most important project is still missing.
Its sad that our manual version control system is now completely corrupted as the zip file is not reliable.
