Nero issues



i had nero 6 in my computer.i then tried to download songs from 2 different
websites.i put them into the express and i saw that the track song lenths
were out of wack.the express added 2 minates to the instead of
say 3 minates it added 2 more minates to it making it 5 minates
doesnt happen with every download website…only a couple.i decieded to
test it by installing nero 7.ok with nero 7 it kept crashing…while using the
wave editor id get"runtime error has encountered an error and needs to close were sre sorry for the inconviance"how can i fix both of these problems?how do u fix a runtime error??thanks
