There is not txt file. I think that would defeat the purpose of a security key because everyone would get the same one. I went through the zip with the guy from DAZ, read through each file name, and have done the same with the program file Clothes Converter sets up on my system. Nor is there any such entry on my DAZ accounts page. I'm assuming PhilC is right and he's probably going to send me one. I've written him and am still awaiting his response. I do find it somewhat irritating, but I suppose I'll have to be patient. Mike
