iPhone and iPad Error=0 when CM93 import

Hi to everyone,

on my mac, I already imported my CM93 world chart. I also tried to import the same data into my iPhone and iPad by the steps recommended in the instruction:
- Zip the chart
- transfer to iPhone or iPad
- share the zipped data to qtVlm
After this, on both devices, after a "please wait" message an error occures:
"Zip Datei CM93_2018_cartes_2014.zip kann nicht entpacken (error=0)"

Does anyone has an advice? Whats wrong?

Many thanks in advance.

Solved: The problem was something inside my CM93 folder. After buying a new set of CM93 folders, the error disappeared. Hope, this helps everybody, who has the same error message.

Solved: The error was somehow or something inside of the CM93 folders. After buying a new set of CM93 dataset, the error disappeared and everything works fine now.
