I have the same issue, I guess it's due to the xunitytalk site being down (forever, it seems), as PCD has noted above. I read a bit o. Twitter and it seems lile the xunitytalk devs might be moving to TVADDONS, so maybe PCD will be able to update kodidirect to download the addons from there once available?!
However, today filmon just wouldn't launch (your filmon is the only one that stays in sync for me) so uninstalled the addon. Unfortunately, I cannot install it again now - nothing happens.
