Now when I enter into the app it says: ERROR! Coudl not start server! Please change the port number using the 'Settings' app. I go to settings but I have no idea what to change it to. This is so annoying!!

I just purchased this app hoping to clear some room on my iphone to transfer photos to my computer and I am unable to get it to connect. I am on the SAME wifi network at home, I have closed ALL other apps on my iphone, I am on the homepage of the app, and I still cannot get it to work. When I select my photos and then say send to Mac it says 'go to this address' and all that comes up is "ERROR", then the alternative site starting with http://192.168.... does not load either.
