Thanks heaps strarup, I can't load the file though :/

I have Maya 4.0, it says "Error: Error reading file"

and "Errors may have occured while reading this scene that may result in data loss.
Please check the script editor for details."

And in the script editor it says "// Error: line 1: Unknown Maya file version: 4.5. //
// File read in 0 seconds."

Seems pretty damn stupid to me that you can't load 4.5 files with version 4
