If you have downloaded the files with torrent, no failures got to be in the files. It's very odd happening on both PC....save a lot! I can give you in this case no more advice.

Recording music:
The easy way is to mute the music in EB, and have wmp separately.
The hard way is to get music files into RTW, for this I'll suggest you search the forums.

I do not know much about music...so I suggest to search this forum and if you got not the information open a new thread in the main section.
