frontend error Magento 1.7.0.2 CE

[leonmex]

Hello we install the plugin

Netzarbeiter_CustomerActivation
Netzarbeiter_GroupsCatalog2
Netzarbeiter_LoginCatalog

And we have in the frontend the error
SQLSTATE[42S02]: Base table or view not found: 1146 Table 'mydatabase.groupscatalog_category_idx' doesn't exist

It seems for some reason Magento didn't run the GroupsCatalog2 setup scripts.
Please run the following SQL query:

DELETE FROM core_resource WHERE code = 'netzarbeiter_groupscatalog2_setup';

Then clear the cache and reload any page. That should trigger the scripts to be executed and the table to be creates.
