Hi there: up until recently I was having no problems but after installing the Nero AAC decoder I am unable to convert AIFF files purcahsed at HD Tracks to make them 44.1 16 bit for my iPod and for CD burning I keep getting "File error reading chunk. [clAIFFHandler::ScanFile]" I deleted the nero codex and uninstalled DBPower and reinstalled it, but that didn't solve the problem. Help! I am running Windows 7 32 bit. I tried converting Flac files I purchased and the converter works for them.
