catagories module & database table issue

i have a clean 4.7.2 install where i had made a taxonomy in order to find that taxonomy menu doesn't work yet with 4.7. so i went on to install the categories module and converted the taxonomy into categories.
now, every time i try to admin categories, i get the following error:

Table '.view_view' doesn't exist query: SELECT vid, description FROM view_view ORDER BY description in /home//public_html/includes/database.mysql.inc on line 120.

could someone please point me to what's wrong, and - more importantly, how do i fix this?

thanks
