As it's opening the game window? Sounds like a Java related issue.
First check in Tools>internet options>Security to see if internet security is set to medium or lower. If it is at custom or higher, then customise it and make sure that Java is enabled (or just set to medium, but not lower).
Doesn't help? Do you have broadband? If so, go into add-remove programs and remove JAVA - all versions that might be there. Go to www.java.com and download again. Does that help?
If that doesn't work do you have Norton? If so close all IE windows, clear temporary internet files. Disable Norton firewall, reload game. Try Shift F5 if it still doesn't work. Does that help? If so you have to configure norton to allow the game to work. Don't leave Norton disabled, anti-virus is more important than FoD.
I can't guarantee that this is your problem, but given that FoD are taking time I thought that this might help. It certainly shouldn't hurt, but may take time to reinstall Java.
