Disappearing Apps?


Hey guys now i usually wouldn't go this far to find help but now i really need it.
Now just recently as i was using brawl textures and having fun with it like most people when my game froze on me and i wasn't really worried because this happens a lot over the past few months since i got the started using texture hacks. But this time when it froze and i tried going back to home brew channel but when i got there nothing appeared the home brew games, the home brew browser etc.
I've tried getting a new gecko OS and looked at my SD card files thoroughly and everything is in the right place exactly where I've left everything last time i looked at it but when i put the SD card inside the Wii and look at home brew channel its like I never put Apps there to begin with.

If ANYONE has experienced the same problem and knows how to correct it Please respond because i cannot live without my texture hacks 

Another thing the games play fine some of the time but other times it it says the disk cannot be read and the disk stops spinning suddenly (but im very sure this has something to do with the cat knocking down my wii when i was away    )
