I was sort of afraid to install and pay for this online. There is so much identity theft out there.. I was just a victim of fraud on my bank account. But this seem pretty secure and was easy to get going.

Error in my ways! I was unaware that I had used the service in the past which voided out my free trail. I then subscribed again and was instantly billed for a full year. When I realized my mistake, I reached out via instant message to the support staff. The service was stellar at best. They assisted me promptly and corrected my dispute which was impressive to say the least and speaks to the integrity of this service.

This morning my card was charged for a yearly subscription as soon as i realized this i canceled my subscription and emailed them to ask for a refund and within an hour my funds have been refunded to my account!

It includes everything I needed to do, and then some. Its much more user friendly then even Adobe itself. But, for the price, and my specific needs, it works great.
