    Try reading what you sent to us:

   There are new adverbs, you will need a compress (or restore 0)

    This suggests that you got a BLEW CORE! message and so have a
broken (truncated) procedure which causes compress to fail.

This is what compress told you to do - and that includes the file that
needs to be fixed and RUN or at least deleted.  But, so long as you
have that broken proc, compress will not work.  Either fix the
problem, or start over with a RESTORE 0.
