Hi Clint, I'm using Internet Explorer 6 (the newest one) on a Windows XP Pentium 4 computer. The connection is DSL. As you can see by my past purchases, I've bought alot from this site and never really had any problem. Up till this last download, the files always DL as a zip, now I have to rename it from an .ez file. I have done that in the past, when I first bought here and always worked fine. I don't get it?? Even today, after you reset it again, it's still coming up as invalid or corrupt!
