Can not get the critical updates....

Hi,
I am using my shared hosting for hosting a Drupal site.

When I go and try to update modules:
http://www.drozturk.com/opublish/user#overlay=admin/modules/update

It gives error:
Downloading updates failed:
openpublish-7.x-1.0-beta7-core.tar.gz does not contain any .info files.

I tried another way
I also installed drush. It seems to work.
I type: drush up
It shows me which modules needs update and I type y.
It says it updated them.
But if I type drush up again. I see that they are not updated (they are again listed as to be updated).
I don't know if it is the same reason...

Should I manually copy the newer modules?

Thanks
Ozgur
