Hi hossamov,
If you register your licence key in your profile on the forum then you will get access to the 'Technical Support' section and you will probably find the answer to your problem.
You do this by clicking on 'Profile' in the yellow bar under 'Ship Simulator Forum' at the top of the page, scroll down to where it says 'Licence key registration' and 'Enter any licence key' then enter your licence key and click 'Register'.
Regards, Dave
