One of the Kodi developers has posted this in the thread

"Seems Argus client has no maintainer and will decay further. If nobody cares we finally have to drop it from our repo."
It would be a real shame if we lost support for ArgusTV in Kodi. Is anybody out there able to fix this issue ??
Really hope support for ArgusTV picks up again. I have no issue paying for a product like ArgusTV (I already donated a while back) if it would help kick off the development again as its an excellent package!!
