Norton Online Backup A2203 error

I just installed online backup and the first two times it tried to backup my files it gets to about 2% and I receive an A2203 error and the backup has failed.  

 

The backup size in 20,000 file and about 11GB

 

Does anybody have any ideas that can get me going?  I really hate to not have my files backed up.

 

Thanks
