Driver issue on my WiFi USB Edimax

I am having an issue installing the driver for my Wifi USB Edimax series FEW 7318ug. I am using Slackware Linux and have been trying to install the driver of my WiFi USB. I always get an error saying “improper module format”. The driver contains support for open source but I cannot get it done correctly. Is someone having knowledge about this that can help me?
