Need a patch for ETrack 2291889

I really need some help with an NDMP problem.  I'm working with a company whose previous IT staff left the department in shambles.  They've got an install of NBU 7.0 that's running NDMP over SSO to a small library, on RHEL 5.0.  After correcting a number of infrastructure issues, we're still getting erratic errors that are mostly code 84 (media write error). 

After a significant amount of troubleshooting, I've narrowed down that my problem is almost exactly described in this post:

For the system, it is recommended that we request the patch for ETrack 2291889, but I cannot find it online anywhere.  The department here does not have their licenses onsite, they're not sure where they'd be in the other office, which is on the other side of the country, and they're not even sure whether or not they have an active support contract.  Because of all these assorted issues, upgrading to NBU 7.1 is not an issue.  At this time, I can upgrade to NBU 7.0.1, but it appears that I will still need this patch to correct the issue.

To complicate matters, the reason I was called in to assist is because the company's office is being physically moved starting on March 1st, and the last backup that was run was done well over 6 months ago.  Ultimately, time is of the essence, and any assistance would be appreciated.

Is there a way that I could get access to the patch for ETrack 2291889?

Thanks in advance.
