Wii System Menu corrupted?

[Scimoxis]

Hi.
I installed the Wii System Menu a few days ago, and wanted to get rid of the stuff that came with the file.
I tried to format it from the settings but it got corrupted (afterwards I read that you shouldn't format it).
Now I've tried everything to get it working again, reinstalling Dolphin, deleting files and installing different versions, but it always results in the "system files corrupt" screen.
How can I get it to work again?

Have you delete the global directory?

I got it to work!
I remembered that I have a daily file history backup of my Documents folder, so i just resetted the Wii folder to what it was on 30.12.2014.
