I have multiple software packages installed and running on my computer without a problem (Napster is my primary, though I occasionally use Yahoo Music and Ruckus), and doubt there would be issues on the MP3 player end. On the off chance there is a problem you could simply use one service for a few days, wipe everything off the player, then try the other.
Hope this helps,
John
I wanted to try the to go subscription service on my MP3 player (Sandisk m230) & wondered if I could use the free trials of Napster & Yahoo both at the same time on my 1 MP3 player and 1 computer. I didn't know if this would cause a conflict on my MP3 device or computer. Anyone have an answer? It would greatly be appreciated. Thanks!
