Hi, I got The Oliphant Tutorial on DVD and when I extract it error message appears "Unexpected end of error" in ele_15_final.zip I tried to fix it by Winrar but it doesn't work. so I decided to dowload it form site. I download ele_15_final.zip and when I extract it the file "ele_14_final.avi" was in it. So which part should I download ? Thanks and sorry about language
