Le site lingvozone.com est-il sûr ?

Write your coI downloaded their Enhlish>Italian Talking Dictionary. I paid a total of $55.00 for the software and DOWNLOAD PROTECTION ????. After paying I tried to get the registration key to enter into the software dictionary so that I could use it. They send me a download or an attachment with .rkf file extention. I could not get the key to enter it. I could not find any such thing as a .rkf file extention. I tied for hours and gave up and bought another dictionary which after paying for they just sent me the registration key as do all the companies I have done business with. I told Lingvo Soft I would like a refund as I could not use their product. They refused. They said I was not supposed to open the file to get the registration key. The download was just to stay on my computer and I GUESS it communicate with the software to enable you to use it??? No matter how I pleaded with them they refused to refund my money. They must really need my $55.00! "mment
