Drush and 10n_update

I had a mistake in the work of drush: " drush status PHP Fatal error: Cannot redeclare l10n_update_drush_command() (previously declared in ...modules/contrib/l10n_update/l10n_update.drush.inc:12) in ... /all/modules/l10n_update/l10n_update.drush.inc on line 31 Drush command terminated abnormally due to an unrecoverable error. " It could be cause I installed 10n_update to "modules/contrib/l10n_update" when it already was in "sites/all/modules/l10n_update". With the hepl of the hosting admin the double module was removed. Drush is working now.
