VeinMiner isn't working (AT ALL)

[JohnSmith2007]

I've deleted and re-added blocks to the block list, I've tried using a different keybind, I've tried all of the options for enabling VeinMiner, And IT STILL WON'T WORK!

I know your post is about a year old but you just can't say "it doesn't work" without giving specifics. What MC version are you using with what forge version. I have Forge ver 1614/Minecraft ver 1.7.10 and it works fine on the client.

check your key assignments, if you are using "sneak" (try sneak).
remove any assigned keys to vein miner (you can do this in the client). The GRAVE below is just an "undefined" key

Make sure the "sneak" assigned key is not RED

If the above doesn't work, remove ALL mods minus this mod and try it again.
If this is for the server-side, best of luck. I am still trying to figure out to get it to

work server-side.
