Blender 2.5 not working

I downloaded the ZIP file for the 32 bits Windows, unzipped it on a new file, but when I try to run it, I get this message:

I re-installed MS Visual C++, nothing
Uninstalled 2.49b, nothing either. (then installed it back)
Installed Python 3.1, nothing (uninstalled it now)

Then I realised I’m getting this message on the Blender window.

After where it says “found bundled python:” goes the direction of where the unzipped folder is.

Any ideas of what may be wrong?
2.49b keeps working.

Try asking nathan on his blog… he’s maintaining the windows builds atm.
