Veritas Backup Exec 9.1 Rev. 4691 service pack downloads?

Hi All

We have a number of different versions of Backup Exec running in our office, but unfortunately also have ver 9.1 Rev 4691. As far as I can tell, no hotfixes or service packs have been applied to these systems. However, neither the Veritas Update link on the menu or indeed any of the links from the Symantec site seem to work.

I know that this software is now years old and is no longer supported by Symantec. However, given the extremely high cost of upgrading to the latest and greatest version, this is what I have to work with. So, is there a hidden location somewhere that I can download these updates / service packs please (at least the latest)?

Thanks.
