I have a problem that nero 5, it nolonger seems to know what a *.ISO file is, it seemed to work last night as I clicked on the ISO file and it loaded nero and asked me to put a blank cd in, i didn't have one, closed nero, tried again this morning and it does not work. Tried downloading another ISO file but it just says 'unexpected file format'

anyone got any ideas?

Are you running the latest version of Nero (5.5.9.17) ? If not, download and upgrade, always a good start point.

well, well
i'd say so as well but before upgrading, read this

Most probably you have a faulty iso file
Did you try to burn it before?
