You don't need to install IOS or to patch IOS.
NEVER TOUCH YOUR IOS with number below 200!
1.
You have a VERY old version of USBLoaderGX. (4-5 years olds)
Start by using the latest version (1 week old).
there's an installer to put latest version on your SD or USB, you can find it in the official USBLoaderGX pinned thread on this forum's section. click on the logo's picture and you will get the installer for windows.
2.
Your cIOS (not the IOS) is old too.
update your softmod (use modmii to update it!)
update to d2x v8 final, with base56 on slot 249 and base57 on slot 250.
3. NEVER use WBFS manager.
I see you are now using Wii Backup Manager, so it's fine.
4. You shouldn't use WBFS partition format anymore.
It's old, deprecated, and it corrupts games.
Format to FAT32. (or convert WBFS to FAT32 with the program located in my signature if you don't want to lose games)
You can continue to use WBFS partition format, but just know that adding new games is deleting part of old games already present on your drive. Old games can become corrupted and will not work correctly. Only the last added game is assured to be working.

FIFA DOES NOT USE IOS56 !
when you use a backup loader, it use a custom IOS : IOS249.
The default IOS is not used at all. Don't ever try to modify IOS below 200.
(yeah, I already told that, but it's important)
The IOS you need to update is IOS249. (see point 2.)
