SolvedMCPatcher HD fix 2.0.1 help

Well I am bored of the default texture pack that MC uses. I also do not want to use 16x or 8x texture packs. So i decided to use the MCPatcher HD fix 2.0.1. I patched minecraft.jar. when i try and add mods to MC.jar, there seems to be a new .jar file. something along the name of minecraft_1.5_1. I'm not sure of the spelling sorry. so i mod both files to ensure that my MC game will be modded. But upon loading i crash. i just need sort of a walk through on what to do after that new .jar file appears. Thank you very much.

minecraft.jar is the only one you need to touch. The numbered ones are backups made by the patcher. Dont touch them. But because you already have, you need to redownload (patch) your game, and try again. Try checking that the game works with the mods while not using the patcher.
