Thanks for this information.

I have made a small test script
use Storable qw(nstore retrieve);
my $storfile ='./teststorable.dat';
my %testh=(
'eins' => 1,
'zwei' => 2);
nstore(\%testh,$storfile);
my $tref = retrieve($storfile);
print join("\n",keys %$tref);
which worked without any problems!
Then I tried to retrieve an file which was produced some time before and get
the know error.
Investigating the dat file yields:

This supports your theory.

Do you have a suggestion for an alternative?
Also I have to check how to migrate all the old storable files to the new
version.
If anyone has an idea how this could work, please let me know!
Thanks a lot
Have fun
