Password manager choked

Did something I know better than to do. Uninstalled Live Update on wife's aunt's NIS 2003 and NAV 2003 while doing some routine maintenance because it was labeled Symantec (my computer experience goes back to when they were not connected) and it looked superfluous. Killed LiveUpdate, of course. System restore didn't. Tried 2 separate dates to restore to. No good. I thought uninstalls were reversible. I could not find any way to do so.
System has been kept up to date and may have had later NIS and NAV versions installed. Rather than uninstalling all of it and reinstalling 2003 from her CDs, I went to the Norton site and found an "update" option which I thought might repair or reinstate the missing files if I installed it over the broken ones and at the same time update anything which was updateable. Turns out it was an "upgrade" link and had a built in uninstaller for the older versions. After downloading that and rebooting to start clean, I executed the "update". Turns out it was an "upgrade" to the latest version, for $70, thank you, which I saw no mention of before I started. All went well, however, with the uninstall of the existing and new install of NIS 2009. Got it all registered and functioning or so it seemed, but now I am informed that wife's aunt can no longer log into her bank account. There is a password manager involved which no longer functions. As I recall, one of the many choices to make is to "delete or retain settings and passwords" or something to that effect. I chose to retain them. Yet they do not work now. I have since returned to my home in another town.
Any suggestions as to what I can tell her to do?
