I bought a copy of the OS to install on a machine we picked up from the meltdown of Studio38. I sent it back and after the promised refund failed to materialize, I filed a chargeback. I had plenty of documentation proving that it flat would not work on my system with one disk for OS and software and a second for application files. After working for about a week, it suddenly refused to boot any application, warning that there was an error, and asking that I run a troubleshooting exe which did NOTHING. They didn’t dispute the chargeback.
