Decided to update my channel list with catseyes latest. Edited as usual then tried to load via VCC (a form of DCC I guess). It loaded a few files then gave a message "OOOPS: ftruncated". Not knowing what went wrong tried again and failed on the first file. Tried again to reload the previous version - failed again on first file. Assuming that I must have a corrupted file during the download I ftped into /etc/enigma2 and deleted all of the files that appeared to be from the channel set. Tried again - success!! Only problem is that now all of my channels are greyed out - message says check tuner config. Tuner config is half right: Tuner A is positioner USALS, and Tuner B is simple but with no satellite (should be 28.2E) - cannot configure it - says nothing connected.
I guess I must have deleted one file too many - but how do I recover without a reload and start again?
