I want to know why won’t yahoo messenger music won’t connect nor while using microsoft tutorials there is no audio since I have installed nero 7 software that came with my I/O Magic DVD + – 20x drive to view a dvd. The dvd moved slow and quality was bad. The system has samsung on it. I did not have the problem before installing nero 7. Are there some configurations I missed that interfer with my computer after Nero 7 is installed? I have had this software on before but uninstalled it because of a configuration problem.
