Problems with FFX4

When I use FFX4 DX2VST wrapper it says “plugin error” when I choose any of my plugs and my sound disappears. If I then open Sound Forge, it won’t be able to play any sound. Windows alert-sounds plays fine though.

All my other plugs work properly.
Anyone have a clue?

why are you going for the dx version if you have the VST version ? I dont get it.

oh, and it may be that you can only use one ffx per song, but I am not sure about that.
