Hi guys, I got this Sony Network Walkman NW-E105 and i have to instal Sonic Stage 3.0. I tried this and it insalled the program without any problems, but when i want to start the program i get this error message "Cannot initialize OpenMG CD Manager" and i am forced to shut down the program. I tried uninstalling and reinstalling a couple of times but it doesn't work. So i downloaded 3.1 but i get the same problem again. I have all the requiremts on my pc that is ask for on the box. I run Windows XP home. Any suggestions?
