the help button should tell you the version or go into properties etc, i find your comment about nero strange as i have 5.5 with all the updates and it works fine with my xp, if the problem is recent why not do system restore to prior to the problems and install?
i put nero 5.5.8 on which just didn`t work. i removed it then tried 5.5.9 and also put a dvd copier on called `dvd movie copy` - some american program. (you have to bear in mind i had no real knowledge of burning at this stage)
this is when the problem started. if i put a blank disk in the rewriter drive and try to use windows xp burning software i get `d is not accessible:incorrect function`.
i did system restore but the problem remained!
i went to the nero website and used the remove nero tools but this hasn`t helped. i`ve posed the question on here at least four times without any success and i`ve scoured microsoft knowledge, i rang nec who supplied the drive and i`ve searched other forums as well but nothing has worked. i figured maybe uninstalling then reinstalling WMP might help? theres no version number in `properties` by the way? can you help johnny??
Its a bit of a cop out and a right ball ache but how much unrecoverable data do you have on your pc? If you have the original discs for your programs you could back the rest of your files on a few CDRs and format the hard drive. A bit drastic but if nothing else has worked it might be an option.
