so, if you read the instructions on how to use it, the way you do it is that you put the
.dll file into the ''
managed'' folder. you can either replace it or save the original file in case you need it for whatever reason. after that, take the texture pack you downloaded and put it on the game's directory.
if it still doesnt work, or this is not the problem, please let me know and i'll be more than happy to help you.
