Norton Ghost 14: error EC8F17B7

Recently (Feb?) installed Ghost 14 and successfully ran initial (full) backup. Incrementals seemed to be going okay, but when I tried to run 4th one got an error message. I searched other posts and found a similar issue (though it mentioned Vista), after reading I tried disabling "search engine support" and was able to succesfully continue my back.

 

Error details:

Error EC8F17B7: Cannot create recovery points for job: Drive Backup of  (C:\). Error E0BB0191: Search engine support cannot be enabled for this incremental image. Error EA3905ED: Required file attribute missing.
Details: 0xE0BB0191

 

I am running Ghost v14.0.4.30167 on a Windows XP Home (sp3) machine, backing-up to a Seagate FreeAgent1.5TB external HDD (USB).

 

Any help would be appreciated.
