I have downloaded the latest version and everything is fine until I try to covert. When I get to the page where I have to select the frames, there is no button to proceed to convert the file. Please help.
Yes this is an issue with Hi-DPI screens: the next/cancel buttons are not displayed. I will release a fix later this week. In the meantime you can just set the dpi of your screen to 100% when doing export and you will see buttons.
