I've downloaded init wife now at 13 gb a download and I have a limit of 90 a month but that doesn't matter. 

Why do I keep getting corrupt file when installing??  This is my 3rd system in the last little while. I had it on my original that died. So I bought a used one and put it on there no problem. But that system died too so I bought another new system and try to put it on there and keep getting corrupt file when I try to install it. 

Any ideas??

i have the newest really slim system now

thanks
