I have a cd rom of Gospel pianist & one of Latin pianist , two AMAZING programs.. My Hard drive recently crashed and I tried to re-install them on my new computer. I was surprised that when I put the disks in my cd drive they were completely blank!! in other words my drive was seeing them as blank disks! I had purchased them several years ago and I contacted PG to find out if there was an issue with Windows XP...I'm still waiting for their response...I tried them in the dvd drive ...nothing..blank!!..its very frustrating...does anyone know why this is??...I would be most grateful for any information..thanks
