Okay first step you have to get hex workshop.
In this picture you see two red squares.
0003 and 0033, 0003 it's just a version number 3, and 3300 it's version number 51
like 3.51
opening he workshop, browsing MainServers, then it gives you about 8 or less places where there is difference between 2 main servers.
so you just click on the result and it takes you to right place, the difference is marked in yellow, you just change it , save and done.
