Is Cambridge still around ?

Yes.

Does anybody know about the status with the 302 problem
with validating IGC files and invalid reported broken
security seals ?

There is one 302 that I am aware of which has been shown to have this
problem, and it is currently being looked at by Cambridge. I have seen
no evidence that there are any other 302s that generate invalid IGC
files (and I own one myself). If you know of one, please contact me
directly via email.
