I am checking out Proclaim to see if it will work for our church. I am going "on-air" without a license as the software allows but the signals don't work. Is this because I haven't purchased the software yet? I have followed the instructions for "following" in logos but doesn't seem to work. I have also downloaded the apps on my iphone and ipad and can control the presentation from either one but just can't get signals. Any help?
