I also am having the problem of loading winamp w/ the 1.04 version. on my windows xp install ive had for a while winamp 5.32 and 1.03 ml_sony and it worked, then that lovely day when 1.04 was released i updated both the plugin and winamp to 5.35 and it worked flawlessly! however i now have a new problem, I currently just made the switch over from windows to linux. and the linux options for sonicstage and sony walkmans is garbage. so i went on and created a virtual machine for windows xp really for the main purpose to install winamp and use your plugin. This is a fresh install of windows XP (same disc i used for my old install of windows) w/ the newest verison of winamp pro, full install w/ Media library I loaded version 1.04 in the plugins folder yet nothing shows up in winamp preferences when i connect the player (and it gets a drive letter in my computer in the virtual machine) nothing shows up in winamp i then load version 1.03 dll in plugins the plugin itself loads and winamp detects the player, however it doesnt work because its winamp 5.35 any ideas at all on how i can load 1.04? is there some other software that i happened to have installed on my old XP install that isnt on this fresh install? updates maybe? thanks alot!
