doctor,
There is the Upgrade Booklet, 0302/E1, for the main TNE/FFS rulebooks. This include rules clarifications and errata to TNE up to 1993, and errata for FFS to the same year. There was an article in Challenge 75 with the full errata to take the first printing of FFS to the second printing. This was dated 1994.
I don't know if there were any updates to either, or indeed any of the other books in the line.
IF you need a copy I don't mind getting you a scanned PDF.
