accidently deactivated master admin and can't access network controls.

I've got a big problem. I was deactivating a bunch of test user accounts, and accidentally deactivated the master admin. Now I can't can access the buddypress network. I can get into the site under a different admin, but it is only tied to the website and not the network. I contacted my host provider, and they said that a restore would need to be done to back it up to the point where the user was active. Before I do that, I want to get your advice as to how to proceed, and if you see any other options.
