Many of us did miss that one. CDR-WIN worked fine on one of my PCs and I don't recall installing the ASPI layer - but I must have at some time. So when I put CDR-WIN onto the other PC I was surprised to find the problem. So I looked up the word "ASPI" on the Forum and bingo. Pleased to have helped.

Incidentally CloneCD and Nero aren't bothered about the ASPI layer.
