You know something, you don't help a lot... And I am sure your behaviour do not reflect the behaviour of all admins. The point is to find a solution not to criticise my compiuter. I told you I downloaded and tried to install it many times, with antivirus on and off, I restart my compiuter many times, I cleanned my registry and finally I totally uninstalled aslain from my pc. You could really help if you tell me what to try to do. Thanks a lot.
