Data Error in Riff/Wave files

I installed the latest WAVE.datatype and I get a data error on Riff files. I've always used Riffs with Sys:Sound Preferences. How can I determine what went wrong?

@Snuffy

You can write to the author and send him the sound that failed on. I hope you removed wav.datatype before installing wave.datatype.

@Snuffy

Make sure you don't have the wav.datatype descriptor file still in DEVS:DataTypes. If you do, either delete it or move it to SYS:Storage/DataTypes and then reboot.

If you still have problems with a file, run the following commands on it and then post the results in this thread f.e.:
list filename.wav
easyhex filename.wav

Hi @salass00

There was no wav.datatype files here. I think it's a case of a unstable system. I went and turned off 'composting mode' and ditched the wobbly optical mouse for ps2 mouse and reinstalled your datatype; all the wave/riff files are working normally now. So the problem appears to be conditions and state of OS4.1 at the time of installing an update! I kind of thinking now of a warm restart before doing any updates. What do think?
