View incorrect on the database

-- HikaShop version -- : 2.4.0
-- Joomla version -- : 3.4
-- PHP version -- : 5.4.35-1byte1
-- Browser(s) name and version -- : FF

Hi,

On the 13th I did an update to Hikashop 2.4.0.
But today I got an e-mail from our hoster that there is something wrong wit the database.
There is an view incorrect on the database. These views refer to other tables / columns that no longer exist. So now the hoster can't make good back-ups/

I don't know what it means, but it has to do with Hikashop, see ERROR below:

2015-03-16 11:28:54,267 dbbackup.utils.mysqldumper CRITICAL [db062963_live] Mysqldump stderr: mysqldump: Got error: 1356: View 'db062963_live.cryp_hikashop_click_view' references invalid table(s) or column(s) or function(s) or definer/invoker of view lack rights to use them when using LOCK TABLES

I hope you can help me with this issue.

Hi Nicolas,

Thanks for your anser.
But I still don't know why these tables exist. But that is probably due to my poor knowledge of databases
Do I have to delete these tables every time?

During the update I had problems installing it in the normal way. Finally I placed the installation files to a folder on the server and install from there. Could it have to do with this?

Anyway:
When I want to delete these tables I get an error that it's not possible.
It says: Error while processing the command (see image)
The table is also in use! (see image)

What should I do now?

Kind regards
Lumiga
