Unable to Access /wp-admin/network

When I try and navigate to /wp-admin/network, I get:

You do not have sufficient permissions to access this page.

I have read as many forum posts and support threads pertaining to this as I could possibly find but can't seem to fix the error.

in wp_sitemeta site_admins I have
a:1:{i:0;s:17:"Pete99-lowermedia";}
this is the name I use to log in.

I made a plugin to help diagnose the problem.
When I echo get_super_admins() I get my username (exactly as shown above)
After I check current_user_can('manage_network') which returns false

What may I be over looking?
Thank You!
