Import/Export file formats missing

All of my import/export file formats are missing. Blender loads properly with Python found. Downloaded Blender 2.49b loaded without problems. I had to reload Blender
after a system crash. Are the import/export formats still a separate Python script?
Thanks

Problem solved…there are apparently missing pieces when downloading only the executable. However, downloading the zip file included the missing import/export formats.

Thanks for your humble mistake, i’ve searched for hours on how to fix this, blender site is down, you posting and answering your own question here saved me hours of frustration. i made this account just to thank you.
