Hi Mackson,
Welcome to the forum. I am so sorry to read of the problem you are having with trying to get Infinity installed, its clear we have let you down and are not making it easy for you to find a resolution. I can help.
I will need your BT account details to look into this for you and I can assure you I will give you a straight answer as to the reason for the hold up. Please drop me an email, you will find the link to the 'Mods' contact page by clicking on my username, under the about me section. Please include the link to this thread as well.
Cheers
Sean
