Norton Ghost 15 sees all logical drives as hidden drives

I have a 1TB SATA hard drive that is partitioned into 3 logical drives.  After not running Norton Ghost 15 for a few months (98 days), it's suddenly seeing all of the partitions as hidden drives.  It didn't do that the last time I used it.  When I try to back up, I get inconsistent results.  The first couple of times I tried it, it allowed me to configure and run a backup, but it didn't actually back up anything.  I uninstalled it and reinstalled it, and got the same results.  I uninstalled it and reinstalled it again, and now it's still seeing hidden drives, but at least it started backing them up (I terminated the backup to finish this post).

I read and followed the suggestion for Norton Ghost 14.0 showing all internal drives as hidden, but it didn't make any difference.

I'm running Windows XP SP3 on a Pentuim 4 box.

Any suggestions?
