That the point!!! Thank you anonymous stranger in a perl. I really had a firewall - which was shutdown. And I did not blame it. But it turned out somehow, that core of firewall was not shut down and did it guard job without any annotation. It stopped strawberry/perl.exe from access ( while perl/perl.exe was allowed long before) !! When I launched firewall again( jetico ) I made permissions to strawberry and it began to work!!! The more stupid question the more easy answer. Thank to all , all , all who supported me. I feel really not alone here in this world.
