The Server Busy reply from TiVo is the key to the problem - it's not responding to requests to download files (probably why Tivo Desktop stopped working as well). Rebooting your TiVo will likely clear out that condition. Also note. It's not a good idea to have both Tivo Desktop and kmttg running at the same time if both are trying to download files at the same time. kmttg will limit downloads to one at a time per Tivo but it doesn't know about other programs also trying to initiate downloads at the same time which can overwhelm the Tivo server and result in errors such as what you are getting.
