Plugin custompress 1.3.5.8 does not work on WP 4.0

Hi, I just install a new fresh WP network.

I install custompress plugin and create a new custom post type.

After that I create a new testing sites, but the custom post type menu is not available.

I alredy use this plugin in the past, and I don't remember that I had to enable it to show the custom post type in the sites.

Any suggestions?

Thanks for your help.
