Dear Mr. Needham.
I don't believe it is Internet issue. I've found that images are being downloaded fine.
Cache folder c:\Documents and Settings\MYACCOUNT\Local Settings\Application Data\Microsoft\WorldWideTelescope\Imagery\ has a lot of folders such as 134741791, 25145512, 7391555 with none-empty png anf jpg files which I can view. All files are 256x256.
I see screen like this.

Also tried to re-install DirectX 9.0c, change resolution of Screen, tried different options in WWT Settings. No result.
Waiting your response. WWT sounds like great tool but we are stuck to start working with it.
Best regards,
Nicki
