Sansa Fuze+ Firmware 02.38.06

I am unable to download the Sansa Media Converter.

I have a Sansa Fuze+ with 4GB of hard disk space. I downloaded the firmware updater last year and updated to 02.38.06 and downloaded the Media Converter just fine.

Recently I reformatted my laptop so I lost the media converter, so I downloaded the firmware updater (currently it says 1.304 while my Sansa is already 02.38.06) again. But when I try to update again, it says that the update service is not available.

Any ideas? Thanks in advance
