sansa updater problem

I am using sansa e250 mp3 & whenever i try to launch sansa updater it always says "It can only be launched by sansa service only" Can anyone help with this problem....????

Please Help...!

Try to remove the whole software & try fresh installation. You can download it from here & then install it.

What does the Sansa Firmware Updater do?
A: The Sansa Updater is an application that checks for the latest firmware updates then downloads and installs the firmware to your Sansa device. The Sansa Updater is NOT a firmware.

The file that runs the updater is located here : C:\Program Files\SanDisk\Sansa Updater\sansaupdater.exe

Create a shortcut to the file and put it on your desk. Edit the shortcut and the target properties, add the following to the end of the line : -iloveit.
So, the line will look like this : "C:\Program Files\SanDisk\Sansa Updater\sansaupdater.exe" -iloveit

Remember, there have been space between the closing double-quote and the Hyphen. Launch the shortcut and the Sansa Updater will show in the System Tray.

I install SansaSvr.exe as a service, start it and plug in my Sansa. Something happens, but no UI. A little spelunking shows that SansaSvr.exe has launched SansaUpdater.exe but there is no UI showing on my desktop. But now at least I can see that the magic command line switch is "SansaUpdater.exe -iloveit". Kill the service, run "SansaUpdater.exe -iloveit" and off it goes and now I can finally update my firmware!
