|I don't know why you would purchase that product...better free ones out there.|
The problem is, you purchase it and look for tech support and it is non-existant...go figure!
The best solution is to hound them till they fix the problem.
Here's a solution.
First of all, which browser are you using for the download?
Try a different browser and set it so it downloads to the desktop. Then install it.
If you can't download it, I would suggest you try on a different PC and then save it to a thumbdrive or burn it to a CD and then use that to install it on your PC.
You should have the license key in your e-mail if you purchased it online.
