Wii Downloads not working

First of all, I would like to thank every one of you for making this site. It's nice to see sites like this that are focused on preserving the history of games.

Now onto my issue. I've been trying to download some Wii ROMs on my phone, but every time I try to download in either Nkit or WBFS, it tells me to wait until my current download is done. I've tested Gamecube and that works, but the Wii ROMs won't download. Any advice?
