I have both composer pro 3.1.1 and composer pro 2.9.1, I am having trouble finding a composer patch, and when I try to connect with latest version of composer pro, I keep getting the error mentioned in above post, I have searched dealer.control4.com, and unable to locate it. Is it better to use 2.9.1 when connecting to the 800 or 3.1.1. Trying to be prepared for tomorrow, I am fairly new to c4, and this is the first 800 I have had to work with, appreciate all the help so far, once I can get connected I’m golden lol.
