I have also been experiencing the same problem. I have attempted to download the latest NAM and it indicates 10mb file size at start of download but at approx 300kb it zips to 100% and closes. Winzip then reports the file as corrupted. I have tried to d/l file numerous times over the past couple of days with the same result. The same problem has been occuring for approx 50% of files I have attempted to d/l from Simtropolis. I am using xp with the latest updates. IE 7. And I have turned off the firewall in XP. I do have a slow dial-up connection. Averaging 3kb/s
