I have a problem... when I press swap to client I get this error:

-->"You need a method of return to use thies feature. If you think this is a mistake, either teleport or relog" . I reloged like 20times and the same error... getting me out of my mind cuz I don't now what to do...
And something else... how do I inject the codes? more exactly where do I write them, or for e.g where do I write or what can I do to accept a pt.
Thx for anyone who can help me in this 2problems.
