Any Ideas?

And sorry Don when i read it back my comment sounded more serious then it was meant to

It's a great suggestion, someone i know had some camera problems like these caused by his pc (or what he did with it to be preciese).

no offence was taken... nothing to apologize for.

A lot of the communication is lost by just writing and i forget that sometimes

David, any luck so far or do you still have this problem?

Stefan, Don't know what I've done(apart from being stupid and not noticing the settings were 3 under) but I did update the firmware, made the correct choice of settings, replace the card and it all came together.
I even played safe and bought a 20D from Simonkit in case it happens again on something important.
Many thanks to all you guys for the help and suggestions.
All I have to do now is justify to my wife the need for "another b****y camera"
Dave.
