Shut down my other tank yesterday and set up new one. Reinstalled RK and now it does not recognize my MLC module. Did the update on My Reef and still nothing. It's like its not even trying to connect with the module. The #4 light on head unit doesn't come on either. I tried another MLC module and same issue. Any help on what to do? I do have the item hooked into the MLC and that does work on both MLC modules I have.
