Help !!!!!!! Wav problem

Help !!!!!!! Wav problem

My computer has as operating system windows xp. I don't succeed in
reading some files wav while I am succeeding in reading other files
wav.I have tried to overcome the problem using some programs
converters, but the converter doesn't pick up me it in input and
exactly fails in the reading of the file wav as fail the players in
to perform it.
Curse!!!!! strange thing... I succeed in reading some files wav
but not others . I succeed in reading them on a computer on which
win98 is installed.
I have now tried to make to turn around two systems (win98 and winxp)
GSpot
to understand if it is a problem of codec:
* * * * well on win98( on computer that reads such files tiresome )
me
it says that for the file wav in matter there is not installed the
codec but
what a wave parser is activated link to an imaginary quartz.dll,
* * * * on winxp it tells me instead that the stung codec there is not
installed and
enough
Curse to Bill Bill!!!! I absolutely have to read these files
wav because recordings of lectures that... I absolutely owe power
light!!!!!
Someone helps me!!! Someone that he intends of codec filters,
and... other grisly devilries of the kind.......
