Message: I'm not connected to the internet but I am

[stritti]

Hi,
I am connected with both computers at one time to the internet (router) and have sent the registration email and registration code via messanger from one to another and worked with paste copy. I tried also the possibility with the discette but got the same error then on the computer where I already have done my registration. Cannot imagine that the reason is that I'm using the same inernet connection because both computers have different IP addresses.
