И как резюме <div class='quotetop'>Цитата</div>
It appears that this problem can be completely fixed (as reported by myself and a few others who had this problem) by doing a clean reinstall, including deleting the files in the "My games/Beyond the sword" folder and the ":/Documents and settings/your user/Local Settings/Application data/My games[/b]
советуют ВСЕ переустановить заново, предварительно поудаляв файлы из указанных каталогов.
