Thanks again Dr Byte for your time..

had adjusted the db prefix so it matches the old/live db in my new config files, though I hadn't included this prefix in the passwd reset script that I ran. (wasn't my password Diva but thank you for your input)

Will export my old/live db again and try the upgarde again, if it fails will try running the passwd reset script again with correct db tables prefix.

Thanks again,
SK
