Couldn't create database for {"timeout"=>5000, "adapter"=>"sqlite3", "database"=>"db/development.sqlite3"}

Fixed by putting sqlite3.dll in PATH. The problem actually was, that Windows 7 didn't show me the error about missing dll. When I tried the same thing on Vista, I got error that sqlite3.dll was not found. But I have absolutely no idea, why this happend only on Win7
