2.47 can't import .obj and other formats?

I just installed the new version of blender(2.47) and it only has three import and export formats. What happened to the rest of them such as wavefront (.obj)??? Are they still there, and if so , how do i import them?

They are still there.
That might help you, if you’re on windows.
