Sansa Media Converter doesn't work

I have a Sansa E270.

The Sansa Media Converter software (of ArcSoft), included on the CD, doesn’t detect the player: It shows the message “Any player detected” with a yellow exclamatory point.
So I can’t convert any video and photo for may player.

But strangely the player is normally detected by Windows XP (in MSC mode) and by Windows Media Player 10 (in MTP mode), but not by the Sansa Media Converter software (in the both mode).

Help me.
Thanks, bye.

see this post. there is also a new version of the sansa media converter. if you contact sandisk tech support they will mail you a cd with the new version
