This gubberation continues. However, I've sort of discovered what's up with it, and most pleasingly, I can fix it, but it has to be fixed every day which is what's cinfuzzling me.
I turn the power off to this thing every night, which I've always done.
Flick it back on in the morniing, and the date in the bottom rh corner has always now reset itself to a date back in November 2003....possibly the date this thing was made?
If I don't reset it, the trouble as mentioned initially on this thread, kicks in, and will continue to play up (no access to emails, strange messages etc,) until I both reset the date and switch off and back on again.
Once that's done, evrything runs tickety boo.
No response from Nick required thank you.
