AMC, disconnects

This newest version of AMC (Alienware Mobile Connect) repeatedly disconnects. And when it is working, it is terribly slow. A text comes on my phone, it shows up maybe 5 minutes later on AMC. The old version worked perfectly, nothing wrong with it except the annoying prompts to upgrade to this poor version. I want to go back but can't find the old 3.3 version. Is it located anywhere?
