do you have any wav file that certainly can be imported ?
any help appreciated, yes all recent updated, all perfectly in shape, SD card works, can load other file types.
Edit: tried audiocity export, 48KHz, linear PCM, short name, short length, still the same error.
Edit2: even updated to 1.1 (it was in 1.1. already anyway) no effect

thank you for any help/ tip
S.
