Toribash
I don't understand, whats the problem?

If it's the download thing, thats just toribash downloading your textures.
Oh, that, i can't help you, there must be something wrong with your uke and coscu files.

Try Re-downloading and installing toribash and then move all your replays to the new one, that should fix it.

Oh, and delete the old toribash.
Just delete the whole /custom/ folder and then redownload your textures... that fixes this type of bug for me, however if it doesn't it could be a rendering bug.
