Hi Maverik,
I'm trying to install community surveys for the first time but when I install cjlib the installation fault.

I got this error:
JDatabaseMySQL::query: 1060 - Duplicate column name 'asset_id' SQL=ALTER IGNORE TABLE `cp_corejoomla_messages` ADD COLUMN `asset_id` int(10) unsigned NOT NULL

I have tried to uninstall it and also delete manually the table cp_corejoomla_messages but the problem still occur.

Can you help me?
Thank you in advance
