If you get an error that says something like "ID conflict" when you start minecraft, there is a simple way of fixing that. Note that you will need to restart any map because block will change on you.
This is originally from http://www.minecraftforge.net/forum/index.php?topic=1059.0
Step 1: install the mods and run minecraft like normally. See the respected mod's installation instructions. This is necessary to generate the configuration files. Once you see the error message note the conflicting mods and close minecraft.
Step 2: go to your minecraft folder. If you don't know where that is, open "My Computer" and type this in: %APPDATA%\.minecraft\
Step 3: open the config folder. You will see several files ending with .cfg
Step 4: remove the two config files for the mod's that are confliting (for example, if it's pixelmon and industrial craft 2, remove "pixelmon.cfg" and "IC2.cfg"). Personally I would move the files to the desktop, just in case I need them back, but deleting also woks.
Step 5: Run minecraft again. This will generate new config files, and forge will automatically re-assign the ID's.
Step 6: If you don't see any error's, congratulations, it works! Create a new world and enjoy! If the error message is still there, double check the mod's and try again.
