There is a known issue with downloading paid bundles via the Tixati client. This likely has to do with how we manage the number of downloads each torrent file is permitted to initiate.
As we don't support Tixati, we advise you use a recommended client (BitTorrent/ uTorrent). Please use the following links for downloading the most recent version of the either client.
BitTorrent Client (Windows, Mac, Android)
uTorrent Client (Windows, Mac, Linux, Android)
