Well, when I try to open the Josh_DefMesh.mb into Maya 6.0, it shows me the following error:

Code:
Warning: Errors have occurred while reading this scene that may result in data loss.
Please check the Script Editor for details.
And in the Script Editor:
Code:
// Error: line 1: Unknown Maya file version: 6.0. //
What should it be? I am noob into moddeling, and I just read some Maya stock tutorials (the temple and the hammer ones), but I want to know how the pros did those models.

Is/Are there any solution for this error? Thanks in advance.
