Are you looking in your classes folder from the Navigation View or the Package View? The output dir is hidden in the Package View, which is why you most likely don’t see them.
If that doesn’t help, please use File > Export > Archive, and export your project to a ZIP and email it to support@genuitec.com ATTN Riyad, with a link to this thread so I know why I’m getting it and I’ll have a look.
