I do believe the installation I made prior to the change is still working, however the issue was with another installation from Mojo, it would not continue because of the PHP ver. I was trying to install a second instance on another blog. The error message said it needed more than 5.2 but less than 5.4. Dumb way to express it, but that is what happened. I wrote and complained they should not be offering products to install where they could not support the needs of the product on the server.
They linked me to a website where it explained that 5.3 was being retired as a standard. So they are using 5.4 now and intend to add 5.5 in the near future. I didn't research the reasons behind this and they couldn't explain how an already installed chat worked under 5.4 but that I couldn't install the same chat product on another blog.
The only chat in Mojo that would install on 5.4 was X7 Chat. I don't see that much development has been made in a while, it's very simple but it works.
