So, thanks to the sale, I picked up Minish Cap, and A Link to the Past on my Wii U (along with Oracles & Ages on the 3DS). I have not been able to download it. Every time I do, an error pops up, stating:
Error Code: 105-3865
Please try again later.
If the problem persists, please make a note of the error code and visit support.nintendo.com
Support Information etc etc
The reason I know it's not a network issue is, I was able to download Oracles & Ages perfectly fine. It's getting rather aggrivating, as I just want to download some games 
Thanks for the help
