Homebrew not working

I'm not sure if this is the right place for this topic, but I'll try anyways. Recently, my homebrew apps have stopped working- I get a black screen with some info on it. The Wii doesn't turn off, so I have to unplug it. My version is 3.4U, and everything worked up until a while ago. I'm not sure what happened. Any help?

Here's what comes up whenever I load something:
Exception (ISI) occurred!
GPR00 followed by numbers/letters
GPR01 followed by numbers/letters
(this goes up to GPR31)

STACK DUMP:
--> numbers and letters --> numbers and letters --> and this goes on a few more times

What homebrew apps?

All of them. Emulators, file browsers... None of them work.

Make sure you're using the latest versions of the emulators.

Even if he isn't, they wouldn't just stop working like that.. :/

You need to pick one specific version of one specific program, and then actually take a picture of all of the numbers before anyone can actually help you.

Some of the slightly older versions of some of Tantrics emulators were giving ISI dumps to some people. They were fixed in the newer releases.

Sure, but the point is that if you have stuff that works, and you don't change anything, it doesn't usually break. What changed?

Okay... I don't know WTF is a ISI exception =P
But let's try the basics...

1. Download the newer versions of your apps
2. Try re-formatting your SD card
3. Do some black magic on your Wii =P

BTW, did you updated your Wii recently, or did some kind of "downgrade"?

perhaps the SD card went bad...- would explain the all-of-a-sudden-ness
