Then how do you explain this to me: I downloaded the client from the official site (uo.com) and it went through quietly on the pirate server RunUO? (http://runuo.theabyss.ru/). I do not think it's about the client!
Teach: let's say I downloaded the publication of 54. Launched and I had people play. Suddenly the publication is 55. The question is how do I upgrade from 54 to 55 that would not hurt my players?
