I can't mount NTFS drive with Paragon NTFS

Hi,
I have activated Paragon v15 and I can't mount any NTFS drive with error "Value XY can not be mounted"
I tried reinstall Paragon and nothing. If I uninstall Paragon then I can mount drive only for read and it works.

Paragon NTFS for Mac 15.0.911

Can anyone help me?

Thanks

Michael
