Motion Plus error

[Fris]

using real Wiimote with motion plus (never unchecked in Wii dialog box, setting always greyed ??)

running Dolphin_x64_r4525

Game sport resort starting

got error "WmWriteData: bad register block!" and Motion Plus never detected.

I saw someone as corrected this problem but what to do with the patch file...
