first i decompiled using the bat file, then i used the recompile followed by the reobfuscate. Then in the 'reobf' folder, and in the 'minecraft' folder i had the 'a' folder(my class file folder) and 'cpw' folder. Inside the 'a' folder all of my class files are there. and the 'cpw' has all the folders down to the network registry class. Then i put my 'assets' folder in the same folder as 'a' and 'cpw' then i compressed the minecraft folder in reobf. and placed it in the minecraft mods folder and tried to run it and it came up with:
