Just to clarify, you were using pyTivoX before, installed the beta, and now it's not working? Before we try debugging it much, have you made any modifications to the pytivo.conf file? If not, can you just press the 'Apply' button and see if it fixes itself? For what it's worth, line 12 should be 'beacon=192.168.1.255'.. I don't believe any version of pyTivoX doesnt write that line correctly... so I'm not sure how that happened... Added note: I notice you have the application in a directory named pyTivoX-1.0.1. I'm not sure if that breaks anything, but it's definitely not needed. Generally, download the zip file, double-click on it. Open the new folder, and drag the application directly into the Applications folder... (don't drag the whole folder.. just the application).
