Just to be sure, can you look for the following lines in our log files and report the two version numbers back?
[App Background Thread 003] INFO com.dokany.java.DokanyDriver - Dokany version: XXX
[App Background Thread 003] INFO com.dokany.java.DokanyDriver - Dokany driver version: XXX
Additionally you can try out the mirror example to see if Dokany is correctly working: For Version 1.4.0 and higher: Is it Dokany or just me? (or maybe Cryptomator :-P)
