Help! No backup chains found!

Folks,
need your help please.

OS info -> Linux me 3.13.0-52-generic #86-Ubuntu SMP x86_64 x86_64 x86_64 GNU/Linux
Ubuntu 14.04 Trusty
duplicity --version -> duplicity 0.6.23

Made a backup of files using duplicity with destination folder "/home/me/backup". All ok. Tons of *gpg files in there.

Afterwards, burned all of those *gpg files (*manifest*, *difftar*, and *sigtar*) in two cds (half of the files in one cd, and the other half in the other cd). All ok.

Then deleted lots of files in the machine.

Now I was ready to restore. So I copied all of the files from cd1 and cd2 to destination folder "/home/me/hopeful"

Then ran:

me$ duplicity restore file:///home/me/hopeful/ /home/me/my_restored_files/

BUUT, got this traceback:

  File "/usr/lib/python2.7/dist-packages/duplicity/collections.py", line 952, in get_backup_chain_at_time
    raise CollectionsError("No backup chains found")
CollectionsError: No backup chains found

So this is the -v9 dump:

$duplicity -v9 restore file:///home/me/hopeful/ /home/me/my_restored_files/

What can I do? I have been looking into this for a couple of hours now and I can't find a solution!
