Hey, sorry, but I posted a question at this thread :http://www.minecraftforge.net/forum/index.php/topic,31016.0.html
but it got locked so I could not ask any follow up questions.
The response was "We do not support 1.5.2, if you want to play that old of a version you're on your own."
But, they are using Minecraft 1.8.7; NOT 1.5.2
As well as the latest Forge currently up for download (forge-1.8-11.14.3.1446-installer-win)
Thanks!
