14 day guide reduced to 7 and recording options reduced?

From another blog I followed instructions to re-boot as my Thomson DTI 6300-16 machine was frozen on the orange light and would not go to red so I could switch on on the remote. However, in re-booting not only did I lose all my previous recordings (which I understood I would) but it has changed the settings. I have tried to change the settings in menu to no avail. There should be a 14 day programme guide but it shows only 7 and when recording it does not give me the option for repeat recording schedules, ie Eastenders, I can only do one day at a time. I have also done the channel search twice but not all the programmes are showing in the guide over the next few days. I have had this machine since Jan 2008 and have never had this problem before.
