I, like many other, was Riped Off by Following "Ask the Nerd" advice. The Web site stated the "XP Medic" was the best registry repair software available. I paid about $40 for the download and the "Key" to unlock it. The Key does not work. I get a error message every time I try to unlock.
I contacted both the Vendor's Site: http://www.laptoptoolbox.com and the money handlers site http://www.clickbank.com to no avail.I asked for a refund from both sites and got ignored. I sent numerous requests. I learned to avoid "Ask The Nerd" advice and any software peddled through "Click Bank"
