Error launching client after transfering the project to a new Computer

Hello,

I restored and old configuration made with other computer to a new computer and everything seems to be ok.

But when I launch the Client I get the following error:

"Can not connect with this profile. Profile key does not match

the server key. Possible security violation. "

I re-instaled everything and deleted everything but I still cannot launch the Client.


I have also removed the controller from my account in order to add it again.

Could you help ?

Thank you
