Norton Online Backup failed (W32)

Backup Failed (W32) what does this error mean and why did I get it? I have 75 GB of backup space, shows I have used 9.14GB of storage (although, error shows I do not have a backup and cannot access any of the 9.14GB already stored).

 

Vista Ultimate SP2 (32 bit)

8GB RAM

AMD Athlon 64 X2 Dual Core 5600+ 2.90GHz
