Photon Mono 2 doesnt find files

Greetings.

I bought a few days ago a refurbished Anycubic Mono 2. A stick was there not Included.

Now i wanted to convert some Files in a Slicer. I tried out the AnycubicPhotonWorkshop and Chitubox_Basic. Both only give me files after i press the Slice and Save in .pm3n the Manual anyways says i need it in .pwmo and doesnt find thereforce any datas on the Stick (Stick is on exFat converted).

The Version of my Mono 2 is 0.0.8 and on the website is no update File shown.

The internet is not really helpful, when i try to figure out the problem. Or i dont understand it, cause English is not my Mothertongue.

Help is highly Appreceated. Thanks for the help.
