issues with wii

[864jb]

I guys I'm having an issue with my dolphin emulator. It was working fine until yesterday. It still plays the gamecube games but it just stop playing wii games. As soon as I launch a wii game it asks to access my usb drive. I have the option to select OK or Cancel. If I select cancel it just pops up a million times more not allowing you to cancel. But as soon as I select ok it immediately crashes. Anyone else had this issue? Any help would be appreciated. Thanks
