Import file formats missing new load

Good Morning, all…

New member and first post. I had to download and reinstall blender after a system cleanup and Norton install. I am now missing all of my import file formats except for the basic 3. Any suggestions on the solution to recovering all of what I previously had?

When you start up does the small console window say blender can find python? If not install the correct python version, for blender 2.49b this is python 2.6x.

Yes, blender finds Python at startup.
