Do you get a pop-up window with the button "Support Form"?  If so,
can you fill out the form and send it in?

Thanks.

The IDV uses the directory as a first guess at the site.

Here's what I found.

I can read in the file you sent with no problem.  So, the problem must
be in uncompressing the file.  For the BZIP2 files, we have to uncompress
them to a temporary file before we can read them.  This is typically
in $HOME/.metapps/DefaultIdv/tmp.  So for this file, I ended up
with a file called KMLB.20050413215519.restore_tmp in this directory.

So, my guesses would be:

1) you don't have permission to write to $HOME/.metapps/DefaultIdv/tmp
2) You  don't have enough space left on that partition.

Is your home directory local or on an NFS drive?  

Is there a $HOME/DefaultIdv/tmp directory?

If so, are there any files in there?  What are the permissions on 
this directory?

Is disk space a problem for this directory?

Sorry for the problems.
