I'm terribly frustrated. I run Win XP Home. I own Acronis TI 9.0. For some reason, when I try to backup the entire drive on CDR or on my usb external DVD writer, I receive the following errors: Error code 502 - write error : this is after going through the wizard and it making an image on one disk but the second the above error displays. Then sometimes, I get E00040007 Error Opening the File, and it states it might be due to low quality disks. I've attempted different options, such as default settings versus high compression, etc. I've burned most of a day and two dozen cd's at this point trying to make the backup. Please help before I return this software for a refund. Terribly disappointed.
