I have a windows 7 and use dds convertor 2 and theres no promblem, and paint.net doesnt allow you to open all of the dds files and its limited. When i use the dds convertor you cant double click on a file to convert it, it aint work like that, you just click on the drop down menu and select a file and even thats limited as there are only 10+ dds files to choose out of even thought theres more than that. Could anyone help with the dds convertor.
