I just tested and it downloads relatively quickly for me, so I don't think it is an issue with our server. I'm not sure why your download would be so slow. I'm not even sure what the settings might be that would cause that. I haven't run into anyone with that issue before.
I could send you the install files and walk you through manual installation if it downloads that slowly it doesn't make sense to wait. It has to be a setting or other installed software causing the problem, but I'm not sure how to debug it.
If you post a US phone number or skype contact information I can call and look into it with you and help you with a manual install.
