I need a list of the mods that you are using.

That's the thing. I tried to install pixelmon and a dragon mount. I couldn't get them to work, but ever since i downloaded pixelmon it was screwed up.

OK, you two both have similar but different problems. Leonshant, I suggest that you create a separate topic for your issue, as it will be easier for people to help you.

Mgkluchar, what steps are you taking to install the mod?

I acessed %appdata% and went to minecraft.jar. I deleted the meta folder, and tried to drag and drop the dragon mount class file into the jar but it wouldn't drop. With pixelmon, i wasn't really sure what to do with it.
