Media Converter Always Failed! Help!

Can anyone solve this problem? My sansa media converter could not convert my local videos and pics!  After I added a video or a pic and clicked “Convert”, a window popped up telling me the conversion failed because of “not enough space” or just giving no reason for failure. Also I can’t find the folder containing the converted file shown at the top of the window. Many thanks to u!

Please ensure that both your hard drive has more than 300 megs free, and the player has more than 100 megs free.  Also, is the video/pictures your trying to convert actually on the C drive, or something else?
