Did you figure out how to fix this issue?
I too editted the jewels.dll and have my local ip in place, 192.x.x.x and the following for the 1234 and ugkshield..
The server Ive run everything smoothly with no errors, however main.exe gives me the error "not found".
PS - I'm new to this and I just managed to create a Season1 Server, and now i replaced everything with these Season6 files but am still using the same host on my vmware. Im just trying things out so everythings local and I doubt I need to open ports right now.
EDIT: Considering im new to this, i tried testing without editting the .dll and i realised the "not found" error still exists, im gonna check my server files now cause im assuming that the client should be fine as long as i put my ipv4 in there.
