Well mariust, it's funny you should post that. I saw that post on the other forum tonight ( hadn't check back here in the last couple of days). I had got hold of a null modem cable and had replaced the firmware, this made no differance. Tried lots of times but to no avail. Even tried to upload default channels but as soon as the loader detected the receiver and I pressed start; of course the bloody receiver rebooted!!! Anyway, I saw the post you kindly copied above on the other forum and read it several times, the bit which I had not done was the last paragraph, disconnecting the cables and uploading the firmware.. I had disconnected the cable and turned on the reciever earlier in the week thanks to timo's suggestion however, it had made no difference. But what I had not done was to disconnect the cables from the back and then return the firmware back to the original version. This I did tonight and it worked!!!! I've now deleted the channels, updated the firmware and added the channels again and it is now working.
Timo_w2s and mariust5 THANK YOU so much for your help, I'm back in the good books with the wife again!!
