Linux doesn't like spaces in filenames...
Here is the fresh copy of the handlers.cfg file (removed old one per suggestion)
/mnt/ext2/Books/Bible/Bible HSC/New Testament/013 - 1 Thessalonians.epub:cr3-pb.app
They error I get is "Cannot open program", so I assume something is wrong with the directory structure or with how the extensions.cfg file is setup... what do you think?[/QUOTE]
