Help with Client

Im using a custom trapped source, the version was 1.1. So I changed it to 0.5.2 and the client had the same version. But when it was loading to go to nexus it was a black screen. Help ASAP

I don't really know what you are talking about but I'm guessing that you are trying to use a client and server of different versions. Unfortunately you can't just change the version of one and expect it to work with the other usually because of different packet IDs.

What kind of client? Outdated hacked client you are trying to update? Please elaborate.
