Wpads do not work

Hi,
I tried to install wpads on one of the websites. There are no errors while installing. Item in menu doesn’t show, but maybe it is because of admin menu editor plugin. When i try to get into:
https://mysite/wp-admin/options-general.php?page=wpads/wpads-options.php

I see an error with no provilages to access this site.

After 3 hours I see that there is no table wp_ads_banners in database. Also in wp_options there is no rows about wpads.

I’m loosing my mind what can be wrong. have you got any suggestions?
