This thread caught my eye. I seem to be having the *exact* same problem as the OP.

Situation: Tried exporting from two different Windows 10 machines. Used the "EXPORT to MOBILE" option from Casino Verite' version 5.6.207.

When I tried to import into 'Blackjack Verite' on my iPhone, I received the message: File could not be read: undefined.

The iPhone version auto-updated as soon as I began the app, so I believe it is fully up-to-date.

I will note that I *have* successfully exported/imported in the past, although it's been several months. Something appears to have broken in the interim.

Thanks
