Backup Exec tape partially overwritten (a few Mb) - can I recover data from previous backup?

We have a Data Server running Win 2k Server, with Backup Exec v.8.6 backing up files stored locally on the server on a nightly basis (assuming someone remembers to swap tapes when I'm not around).  Our tape rotation system is very simple and we use 'overwrite media without prompting' to simplify unattended backups.  ('Bad idea' someone will probably tell me).

Having lost a number of important files from the data server (user error - not me I hasten to add!) I was attempting to restore from the most recent backup tape.  Unfortunately, I didn't realise a previously scheduled backup had not happened, and when I inserted the tape, the scheduled backup immediately started.  I cancelled the operation as soon as I realised, but around 40Mb of data had been written to the tape.

I have attempted to rebuild the catalog on the tape using the Device: Inventory: Catalog option, but this simply gives me the catalog of the new, aborted backup.  Is there any way of recovering files from the previous backup, which presumably still exist in some form?  The original backup was around 20Gb of data - the files we need are just a few Mb of Excel spreadsheets.

TIA,

Carl
