Error:Unsupported Filename

I get this error message no matter what type of video I am trying to convert.  I have tried .mov, wmv, avi.  I have the current versions of Windows Media Player and Quicktime.  The file I want to convert is only like 38megs.  I have an e260 with it set on MTP mode. My converter is the Arcsoft version.  Is there a better one to get.  I read something about a version made by intervideo but I can’t seem to find a place to download it.

i think SanDisk just put this on their downloads page
