Blog Creation Problems when WPJobBoard Plugin Activated

Hoping someone can help me figure this out.

I'm having an issue with a recently purchased plugin (WP JobBoard plugin).

When it's activated, I can't create new blogs successfully in WPMU. When deactivated, individual and group blogs can be created in the appropriate subdomain, with the appropriate path, as expected. For example, my site is so the blog "texas" is created in when functioning normally. When this plugin is activated, a blog created would have the path

Can anyone help me fix this bug. I believe it is probably a simple tweak, but I do not some assistance in how to do it.

Thanks so much.
