Homebrew Installed BootMii Not - MotionPlus

Hi, just a few questions. Very new to Wii. Installed Homebrew Channel correctly. (It shows on Wii Menu 4.3). I used Letterbomb with the correct Mac address. To my dismay as I have seen in some forums, the controller I used is a MotionPlus controller. I have another of these and a regular Wii controller.

I was hesitant to install Bootmii for fear of not being able to revert to the original settings (Is there anything out there for this?)
When I loaded the Homebrew Browser (that I extracted to a new folder I created called "apps") from the Channel. It then failed after some dialogue screen that was "Extracting the image files". I now cannot use either of the MotionPlus controllers or the regular controller to bypass the Health/Safety warning and no cursor shows on the Wii 4.3 Menu.

Is there a way I can install Bootmii? Is this what I would need to do? Presently unable to use any of the 3 controllers I have. Desperate for a fix. Pardon the play on words. Please help?!
