Return of Reckoning

I have all 5 mega files downloaded, when I got to open them, it is prompted me to use a program, from store? how do I get them to unzip and install?

tried it, it wanted me to buy or install another program, last time I did that...got the old whammo malware!! didn't trust it!!!

I am really pc stupid, I attempted to download the clients, but for some reason it stops and pauses.

Is there a link where I can download one pig download instead of 10 small ones? or is those two the only options we have? the mega and normal ones.... I am soo happy I found this and I am fired up ...
