jit.gl is not working on Windows

Hello!
I have a technical problem with Max.
I have Max 6.0.8 installed in my Windows 7 system. I am doing the tutorials for Jitter. However, all the tutorials that contain jit.gl objects ( for example, Tutorial 32) do not show anything on the pop-up small black window: It is always black.
Then, on the Max window I have the next error:warning: couldn´t create context, trying without depthbuffer
warning: pixel format has already been set to 4, cannot set to 2.
jit_gl_create_context: multisamples: GL Error: Invalid enumeration

Then I opened the Tutorials in a Macintosch and they work perfectly. I assume this is a compatibility problem between Windows and Max. How can I solve this?
By the way, I have also tried the latest version of Max 6.1.3 64-bit

My windows system is Windows 7 enterprise 64 bits

Thank you very much
