I have been helped a friend try and fix his pets @Adrian_ and his hotel will not take any new emu besides the one we have wrong which I think it configed weird (instead of IP we had to put "localhost" and you can still connect when your not on the vps) well anyway anytime we try a different emu with the same config or a different emu with different config settings IT DOESN'T WORK and pets disconnect you which is what I really want to fix.
We have changed the swfs
We have changed the habbo.swf
We have changed the pets swf's
We get this error:
