Hi,
Can you use the "mysqli" drive plugin ?
The actual error message does not indicates the error even if I think that it does not find the config table.
At this moment I will think that during the install, HikaShop does not have the right to create any table, so I will ask you to check that Joomla still have to right to create tables in your database.
It is just a supposition but with the current information, it is the first idea I have.

By the way, do not send me private message, use the "contact us" form instead.
