ive just installed an update to nero 5.5.10.14 so that its compatible with my dvd writer,it worked the first time i started it no probs(nero classic) but now everytime i start it it opens nero xpress,ive even been into the instalation folder and tried starting nero classic from there but still nero express starts,,anybody know why this is happening and how to rectify it,,any help greatly appreciated:)

I had the same problem, I uninstalled it and then installed the new Nero and it worked fine.
