So, I'm paying $19/month for WPMU to get access

So, I'm paying $19/month for WPMU to get access to BuddyPress. I get constant pop-ups telling me I need to upgrade to Premium.
Is there actually some reason why I'd want to pay MORE than this for a plugin? I can't even get BuddyPress or Membership to upgrade or even work correctly because it mostly just tells me to upgrade or update.
And when I do try to update, I get this recursive progression that never actually updates the file.
I'm feeling like I'm being swindled.
