I've been unable to update the guide for the last couple of days now because i receive an error stating that my region or timezone is incorrect, or something to that effect. I've double checked things through control panel and my region and timezone settings are all correct and remain unchanged.
Since this began happening i've also noticed the guide has started listing channels i've specifically blocked, so they therefore show "No data available". It actually defaults to these "no data available" channels and i have to scroll up to find the properly listed channels. It's warning me that my listings will expire in a couple of days if i don't download an update, however it simply refuses to update. The internet connection on this unit is working fine.
Any help or suggestions would be much appreciated.

|edit| Just as an update, i'm now no longer able to even view the guide. I simply get an error stating that the guide is unavailable for my country or region. It prompts me to "set up" which i do, and it then states (after a failed attempt to download) that there is no guide available for my country or region. Annoying to say the least.
