So I got some client thing, followed to instructions of dragging HD texture pack into minecraft.jar folder in winrar. I thought everything was cool and stuff so I ran Minecraft through the client after doing the "Patch" thing, and my Minecraft would open but I would be stuck at a black screen. I deleted my minecraft.jar folder, and reset everything. I believe the pack i attempted to download and implement was Mixcraft HD.
If anyone also has a suggestion for me as to a better HD texture pack that does not majorly change the look of blocks, but rather enchances the quality of them, please let me know.
