I did try the dedicated chat. Their answer was to look into using IIS. However it's not something they support.
I did find one way that I'm trying now. I just created a new directory on one of my URL's. I gave this URL unlimited disk space, and I'm sending a three gig .rar as I type this. I think I can just use the RDC access to move the file to the desired location. Once it's there I can unrar it and run the software. (I hope) I tested this with a small .jpg and it worked.
Thanks for your reply. I am so new to this it's not funny.
It's a shame more people don't use this forum. It would be great to have more answers already posted.
