You pasted it wrong.
Step 1: Download it.
Step 2: UnZip/RAR it.
Step 3: Copy the folders inside.
Step 4: Paste over the orignal folders in: [LIero/Data/] That should give you the results. If that dosent work, don't copy the graphics. I only did a few edits that arnt even worth it. If you can't get liero to work, redownload the superpack found
here.
