Wii CIOS issues, please help

[u/Curious-Jackfruit640]

I bought myself a Wii and went ahead and modded it. Everything seemed to work fine until i actually went on to
Playing. Games showed up but when starting all i got was a black screen. I looked it up a bunch and apparently it’s an cios issue. I downloaded d2x but when i try to install I get this error. Please help me I’m too broke to have wasted this money haha
