Problems with version 3.7.1, 3.7.2, 3.7.3

I had the version 3.7.0s006 build 1015, when I upgrade to version 3.7.1 the users aren’t available to navigate. Now i have an organization with both versions, in the AP minis with 3.7.0 the users can navigate, but in the APs with further version they can not do it. The service is with TotalPlay.

The problem is than i can’t find a way to go back to version 3.7.0, is not any more available.

Can anybody help me?
