I downloaded Omaha Charlie sector in a few seconds and I have DL manager and the icon had 3 colored type circles in on a white sheet of paper and I clicked on the Omaha Charlie sector DL and it says windows cannot find this file, in order for windows to open this file it needs to know what program created it. Then it says search for it which is unreliable or select a program from a list. WHAT DO I DO!
sigh, if it's a .rar file you have to get winrar. http://www.rarlabs.com/
