Reset Categories after trying to use multishop unsuccessfully

[Opting]

I tried using multishop, which caused a big problem with categories.

I now disabled multishop, using version 1.5.4.1 and reset categories with this code:

 

TRUNCATE TABLE `ps_category`;

TRUNCATE TABLE `ps_category_group`;

TRUNCATE TABLE `ps_category_lang`;

TRUNCATE TABLE `ps_category_product`;

TRUNCATE TABLE `ps_category_shop`;

 

This deleted all the previous categories, but I needed to come back how

it was before, having "home" as the default category.

Now, there's no category at all, how do I get to have the "home" category

back on? As it is now, I cannot access category at all. The system fails

to connect.

 

Please Help !!!
