Downloading error

[zanzibarbob7]

On my laptop I am trying to download the latest build and I keep getting this error. I have downloaded RAC on my desktop and had to wait for the disk to get Revit on my laptop. The disk shows an earlier build, by a few days, and I want to make sure that my project will synchronize successfully. I'm running McAfee and XP Pro on both computers. The only difference is the laptop has Explorer 7 and the other 6. What am I missing?

It could be any number of issues really. The 2 main ones to look out for is that your using the latest Internet explorer and that you have service pack 2 installed.
