Approve computer

[callimuc]

After I didn´t use my Account for almost 1 year with a running gold subscription I came back a few days ago.
When I wanted to start my RC client (not Client-RC) I realised that my password was not saved anymore. After typing it in again, I now always have to approve my computer before I can use my RC. This does not happen with the client or the Client-RC. It also keeps repeating everytime I restart my Computer (or maybe the RC not sure).

Is there any way I can fix this?
