Windows Media Player SP404 issue. Help

[Heat Vision]

so for some reason when transferring wav files off of my sp404sx sd card onto my PC, sometimes ill click on a file and windows media player will hit me with....

The audio codec identified by the format tag 1 is required to play this file. To determine if this codec is available to download from the Web, click Web Help.

some files play fine, others result in this message. Im confused though. anyone know why this is happening to certain wavs and not others coming from my SP?

i use winamp classic, but if you want to get dirty load it in irfan viewer hex editor and it might give you a clue.

thanks for the responses guys. Yeah it just seems to happen randomly. im able to play it in other media players but its annoying that i cant play it through my default player.
