Error Loading ParamBlock2

[rmejia]

I am getting an error when opening some old scenes (from 2008 ):
Error Loading ParamBlock2
Invalid file - only partially loaded.

Attached is a small piece of one of the scenes that produces the error:

If I open the scene on 3ds Max without V-Ray installed, the scene opens fine. I then tried changing the renderer to Scanline and opening it again on Max with V-Ray installed, and this solved the problem on some scenes, but not on another which keep giving the same error which ends up crashing Max.

Regards,

The problem is in V-Ray RT; some of the nightly builds had some parameters in the parameter block mixed up. This was corrected a few days later, but any files saved with that version of V-Ray RT will have this problem.

To correct this, rename the file c:\program files\autodesk\3ds Max NNNN\plugins\vrayplugins\vray_rtmaxNNNN.dlr, open the .max file, assign the Default scanline renderer as the ActiveShade renderer, and save the scene.

Best regards,
Vlado

This is rather old, but I am having the same issue on a scene. The scene is only three months old, but I can't open it. I am getting the Error Loading ParamBlock2 error.
