I just installed Sonicstage 3.4, and it works fine with my MD. But with my NW-E405, it won't let me put songs on it because it gives me an error saying Sonicstage 3.4 won't support the NW-E405! It says I have to delete all the songs on the E405. How can I do that if Sonicstage won't read the E405? Well anyways, can I have 2 different Sonicstages on my computer? For example can I have 3.0 and 3.4? Thanks!
