I have Save & Recover v2.0 on an XP system. I burned my own Recovery Disk when I purchased S&R online 18 months ago via a download from Symantic. When I tried to use the SRD now for the first time, it wouldn't work at all - I just got "Checksum failure" on recovery start-up. I also can't burn a 'custom' disk as the program can't read the existing disk either. How do I start again and burn an 'original' SRD? [I can recover individual files and folders ok].
