Trying to get Full Screen Preview in Windows 7

Hi,
I hope someone can help me.

I have been using Nikon wireless transmitters WT-3 and WT-4 with Pixagent ITP Pro 2.0 and Windows XP on a laptop using an Adhoc connection.

Now that I have upgraded to a new laptop with Windows 7 Ultimate 64bit, I cannot get ITP to work either when loading directly onto Windows 7 or using the XP mode. The best I can achieve is a wireless connection and an FTP failure.

Can anyone suggest a solution or even another program to use that will allow the pictures to flash up as a full screen as they are taken and transmitted to the laptop.

Your help is much appreciated.
