Give it a try, tell us what problems you run into here.
Z71, I'm wondering if you may be running into a firewall issue or something similar. Are you running any firewalls? And if so have you tried temparily disabling them to see if that helps?
Zubaz, You should have some error logs in: C:\Documents and Settings\All Users\Application Data\Stardock\Impulse\Temporary could you please send those to me.
