I downloaded the VMS sdk, followed instructions to the tee (by the way, nice detailed instructions, Ryan, those are always appreciated), installed it, everything compiled and linked but winamp 2.x/3.x will not list my plugin and report a directx8 error. I suspect the problem is due to the installation of the dx9 sdk and the VMS framework not being compatible. I couldn't find the dx8 sdk from MS and of course in the spirit the MS way of doing things, DX9 sdk is un-installable.
What is my next step? Ryan, any plans to update the code to make use of DX9?
