Yes, I can read it, but what use is that to you?  Given that it is someone 
else's copyright work, I am not at liberty to redistribute a different 
version:

   hblm and associated programs Copyright 1995 by William DuMouchel.
   Permission is given for not-for-profit redistribution of the hblm
   programs so long as this About.hblm variable is included unmodified.
   Please report problems, failures and successes of this program to
   dumouchel at research.att.com

The reason for the error is that it appears to contain invalid S data 
frames.  (They are in invalid in R and in current S-PLUS, but they seems 
also to have been invalid in S3.  Restoring dumps used to be one way to 
create invalid objects, but many of the loopholes have been plugged in R.)
