I have a fully-functioning Version 12 project; I installed Version 13; I exported the Version 12 project but it fails to load into the Version 13. I first get a message that the project is Version 12 and that it will be converted but then it fails with "An error occurred while loading the Project. ( A local file header is corrupt )."
I have tried every variation of the V12 export process, selecting and de-selecting all the various export option tick-boxes but with no success.

Hello Chris,
The project seems to have a large size, in this case you have to follow this steps in order to import it in version 13:
-Once you have the .iwzip file, rename it as .zip (if you do not see the filename extensions you have to enable them from the Windows control panel).
-Then extract the contents of the file into a folder, you can use a default program like 7zip or select "extract" from the Windows menu.
-Select the contents you have extracted in the folder and recreate the .zip storage (to do this you can use either the Windows default compressor or 7zip).
-Then rename the file you have just created from .zip to .iwzip, so to import it into version 13 by clicking on the specific button "import" and by selecting the file.
Please keep me updated.
