Click on the ERecovery CD purchase and you should be able to get a replacement disk. They run about $20 plus postage but that is a small price to pay for having the correct disks.
Most Acers have a recovery partition but I am assuming you have tried that.
During a Vista install, much more is installed than you call for but only the things you purchase are activated.
The best example would be Shadow Copies, which is not available in Home Basic or Premium. If you purchase a Vista Home Basic or Premium and then upgrade to Ultimate, Shadow Copies is suddenly available in Ultimate but you will see previous versions for the files that have changed, even for the time that you had Home Basic or Premium installed. Strange but true.
