Yes I think you can reply to their email . I have reported another problem too and hope to get an answer. The app crashes too sometimes if you want to drag a folder into the app (creating a new data disk but no new disk is created yet). Maybe there is a problem with long folder names. But this problem does not exist on all folder names.
Here is the answer from Corel for the -111 error:
