Query: Don't buy if you plan to play on computer or portable device

I LOVE Sarah and was excited for the CD. I'm very disappointed that it skips on my computer, despite the fact that my system meets the requirements detailed in the CD's software. While I understand they must combat piracy, they need to find a way that works. I PAID for the CD and I still can't listen to it! I'm also disappointed that Amazon does not indicate when a CD contains this garbage, so that I'll know what NOT to buy in the future. This CD is being returned to Amazon tomorrow!
