I'm sorry. There appears to be something wrong with your account on Telerik.com. I've notified our sales team to see if they can figure it out and fix it.
The link I sent you is supposed to bring you to a page like that shown in the first screen shot which is
the download for the offline installer. Instead you're getting a blank page like that shown in the second screen shot.
To work around this problem I setup a DropBox link to the offline installer for you:
I cannot guarantee how long this link will be valid for, but will leave it there for at least 30 days.
