WPMUDEV Dashboard thinks I'm a free member. Whitelist?

I've read on the support pages a lot of different ideas about how to fix the problem of my dashboard plugin not working, but so far none have worked. I just read a thread about having my IP address put on the "whitelist" by posting my IP address here. So here is my IP address: 23.239.9.61 but I'd also like to know how I can keep it from happening again. Any other ideas would be greatly appreciated. Thanks.
