Wavread doesn't work in 5.03 ?

[Tinia]

Hi,

I'm trying to read longer wave file (in CD quality, normal single). It seems 
that loadwave crashes after some reading, but I do also have problems with 
waveread - it says (I did stacksize and gstacksize to 'max'):
-->x=wavread('zvezdica.wav')
 !--error 44
Wrong argument 2.

at line     103 of function wavread called by :
x=wavread('zvezdica.wav')

On same PC, matlab loads that file without any problems. What am I doing 
wrong ? Any reliable and robust wave reading SW ?

Thanks in advance,

regards,

Bulek.
