Auto Content Generator Install Problem

I’m trying to upload “auto content generator” and I followed the instructions, and when I try to go to the page I’m supposed to, to install it, I just get this, instead of the install screen.

“Table ‘rareauto_rareautographcollectionblog.wp_categories’ doesn’t exist”

What am I doing wrong? I have tried deactivating all plugins, and setting the template to default.

Can somebody help?

Thanks.
