blog-types-config.php error

I just installed the blog types plugin. the db tables are there.

I am running this on a home dev machine….every other plugin has been seemless so far.

I get

Fatal error: Call to undefined function __() in C:wwwvhostslocalhost_wpmuwp-contentblog-types-config.php on line 75

when I run the blog-types-config.php from the browser

line 75 is:

$blog_types_branding_plural = __('Blog Types');
