cant mine some blocks

[TeemingNinja]

Recently I've gotten into modding and I downloaded this vein miner mod to make Minecraft easier so I dint have to spend house mining blocks. The mod works on most thing but it seems not to like big chunks of blocks. By that I mean Stone and Dirt. These are the 2 block types I would like to mine the fastest but it doesn't seem to work. I went into the config and unadded these blocks then added them back in (Same with the tool types) but it still wont work. If anyone has anything I should try please let me know.
