Thanks Jerry and Charlie. At least I'm not the only one experiencing this oddity?? I wonder what makes Jim's setup different to ours?

Jim. Many thanks for the great tip about accessing the error log. From that I can see that the full message reads:
"Audio Conversion Error: Media Foundation failed to convert to .wav The error number is -2147024864 [2019.617.0, 09/03/2019 16:42:17]"

(Another similar message has a different error code of -1072875819. They seem to be the only two codes displayed).

If I get time today I might see if pre - converting the mp3 to wav in Adobe Audition and then trying to load into BIAB 64 ACW works, but still curious why it will convert in 32 but not 64??

Thanks guys for you help so far.

Kind Regards

Kev.
