CIOScorp on 4.0u

I have:
-Installed CIOS rev 13
-System menu v4.0u using waninkoko's updater
-Preloader
-Installed CIOScorp
-Used the IOS60 installer, no to IOS 61, yes to IOS60, yes to patching ios60, no to shop channel
-Set IOS249 as system menu IOS (because it said my system files were corrupted)

I can't run games using the disc channel, because obviously I did something wrong. Can someone help me out?

 

So I should install CIOScorp, IOS60BF, and then Preloader?

 

I installed CIOScorp, IOS60BF, reinstalled Preoloader (the system files were corrupted, so i booted to hombrewchannel and installed preoloader again). I booted up my system, but it's a black screen.
Is there anything i can do except sending it to nintendo?
Sorry, stupid mistake. Ignore this.

EDIT:
Now i have the System Menu IOS set to 60. The disc channel spins longer (as opposed to a fresh, new wii) but still results in an 'unknown disc' error.

2nd EDIT:
For some reason, it now works after reboot.

3rd EDIT:
The disc reads, and the disc channel displays the animated banner, but during the first loading screen (after a profile has been chosen), the system reports that the 'disc could not be read'.

 

Sorry about all the quick edits, I got nervous and made constant updates.

 

These discs all worked before. And they run fine, up until after I choose which save file I want to use. On the first loading screen of any game, it gives me the "disc could not be read" error.

 

I've tested it on various games. They all boot, and their banners display, but after you choose a save profile and it starts loading something (or depending on the game, it might be loading something upon starting the game) it gives the error "disc could not be read".
These games all worked fine on 3.2u+cioscorp. I do not understand why they're not working with 4.0. Any help or guidance would be appreciated.

 

I'm using the cioscorp package from [email protected]
Is that the wrong one?

 

Would reverting my CIOS to an older rev. do any good?

 

After a lot of reinstalling and messing around, it seems my problem was that I had the hack "skip disc update checks" enabled in preloader. Now things seem to work fine.
