Suddenly missing .DLL file (ACAD2000i)

[cfee]

I just clicked yes to download my Norton updates. Suddenly my AutoCAD 2000i no longer loads. I get a message "...bad or missing AC1ST15.DLL " and the AutoCAD fails to load.
1. Can I just replace the file?
I'm using a borrowed with permission (loaded on only my computer) LICENSED version of AutoCAD 2000i, but the CD is not available. I really need to get this work done quicker than they can get a CD to me, and I DID NOT bootleg a local copy.
2. Can anyone help?
Thanks,
