You have an odd mix of Wanin v19 and v 20 cIOS and old Hermes/RodriesMod also.
Wow haven't spoke/heard Spanish for almost 15 years,didn't understand any of it, luckily I know modding Wiis. That guide is outdated, By installing Darkcorp, you put older IOS versions w/old hacks onto your Wii, not to mention it is only any good on old Wii. If you can play games off a Burned disk this WILL stop them from loading using the Disk channel. You will HAVE to use Neogamma or USBLoader GX to play your Burned disk games.
Download ModMii http://modmii.zzl.org/ install it to your computer. It'll put a couple of shortcut on your desktop, run ModMii Skin. Type i agree, yes first time modding/updating, 4.3, U, Pick any exploit other than Wilbrand (won't be using it), 4.3, select any channels you want, No same boring menu, No, leave save spot default, click next and then finish. All the files will download to your computer including a guide.
Transfer anything you have on SD card off to your computer so it's empty, then copy the CONTAINS of the COPY_TO_SD card to Wii SD card should be 9 items. Rename "COPY..." folder to "Wii Mod Files"
Because your already modded, you can launch HomeBrew Channel and start with #4 Priiloader (from the ModMii_Wizzard_guide.html) Once you've finished the guide remove all the files you used from SD card. Run ModMii Skin again, this time choose USB Loader setup + guide. Say HDD WBFS don't want to change, both, it will save to new "COPY..." folder (that's why you renamed old one). Copy the 3 folder to SD card. Get http://usbloader-gui.googlecode.com/files/USBLoaderGX_Installer_v1.8.exe you'll have to have you SD card in your computer and connected to internet when you run it. This puts the newest version of USBLoader on your SD just point it to apps folder on SD. Now copy any programs you saved from SD back to SD card making sure to NOT overwrite the 3 you just put on there, (WiiFlow, USBLoader CFG, or USBLoader_GX). I think I'd only add Hombrew Browser, Neogamma, MPlayer and WiiMC back to SD.
Now that your Wii is up-to-date and properly modded everything should work.
