I have a new computer (running Win XP SP3). I wanted to do a fresh install of 3D Max and the Plasma Plugin. Now after following all the tutorials (including my own

I get the "<C:\3dsmax7\plugins\PlasmaMax.gup> failed to initialize. Error code: 126" error.
To my knowledge this means that I am missing some DLL files. Of course I've copied all the files that I found in URU's installation folder. So something else must be missing.
What about the files
Nx*.dll
PhysXLoader.dll
They are mentioned in the Wiki as being important to the plugin but I can't find them in the URU folder nor on my computer. Do I really need those? If so, where do I get them?
Please help me get this thing set up correctly

SHORT UPDATE: I've found PhysXLoader.dll in the installation folder of my graphics card driver. I copied it into Max's main directory. Also I found some files called NxCooking.dll which I also copied. Still I get the same error message and can't use the plugin.
