The fact is, I had downloaded the application. Had run through all of the initial set up, received a license number, and then ultimately found out that my license number was no good. Just what kind of application are you people trying to push out to the public. I'm not even confident that this app does much more than simply deleting temp files. I have tried to talk to customer service about the issues that I am having. I am simply told that I need to get a new license number....AT MY OWN EXPENSE!!! I haven't even used my original license number. I had to wait more than 3 days just to get any kind of initial response from them! I told them that I since I was being treated like I was, that I would make sure that they would be sorry. So, I really do hope that you take the time to review this, I really do hope that you choose NOT to use this application. I really do hope you choose not to be a statistic for failure as I was. Learn from my mistake, I beg you!
