I am at the end of my rope and angry. 
What is it with this new Pro version?
First of all, send out an e-mail when you're completely changing a product I'm using. I all of a sudden couldn't view anything while away from home. I'm on a Macbook Pro and iPhone 5s.
Why is this?
I'm in tears trying to make this thing work. I don't get it. It doesn't log pictures and I can't see the feed unless I'm on the same WIFI as my iSight that is being used on the computer running the software. Ridiculous. Anyone that can help, I'd really appreciate it.
First off, my apologies for the confusion and the tears!
iCam Pro is a separate app from the original iCam. iCam Pro is similar to iCam in that it allows you to view your webcams from your phone, but the two apps use very different audio and video compression algorithms, so they are completely separate. iCam Pro also has some additional features and functionality, as seen in this comparison chart:
http://skjm.com/icam/The original iCam app is still fully available and functional, so you do not need to use iCam Pro if you do not want to, or if iCam already suits your needs. You can re-download iCam to your phone if you deleted it (as well as the original iCamSource to your computer) and things should continue working without issue.
As for "sending out an email" that you mentioned, Apple doesn't give app developers the contact information of our app users, just in case you were wondering.
If you are wanting to use iCam Pro from outside of your local network, you do need to either purchase a monthly service subscription or the one-time lifetime purchase. iCam Pro is free on the App Store, and allows you to connect via local WiFi only for free. To connect from outside of your local network the iCam Pro Service does need to be purchased.
But again, if the original iCam was working for you, you can still continue using it.
