The mod looks great so far,
Thanks in advance.
I had trouble at first here too, but check:
It looks like a bunch of code but the options are all in there with the descriptions of what they do.
To help you more directly, look for the line that says:
Possible options are; topleft, topcenter, topright, middleleft, middlecenter, middleright, bottomleft, bottomcenter, bottomright
You can open the *.cfg file in notepad. I'd also recommend getting Notepad++ (http://notepad-plus-plus.org/)
If your still having trouble, or even if your just a little board, please check my site: http://minictm.com/mod-pack/
It's the Armor and Potion HUD, and damage indicators, and it has the config files all set up to just copy over. Also there is room for REI's Minimap if you use that. Credit of course all goes to the original creators.
Special thanks to bspkrs again! (@bspkrs: Please let me know if I can help in any way!)
