I was just floating around my Nero 7 Premium SmartStart and noticed that I accidentally installed my Nero 7 Ultra Serial into Nero 7 Premium. Is this a problem? Also, I had installed an older version of the mp3pro files due to the ones included in Nero 7's initial release from this site to correct the popping/glitch issues I had and was wondering if the 7.0.8.2 and 7.2.3.2b updates fixed that and which update i should go with. I've heard nothing but bad things with 7.2.3.2b.
