You have put MV as the engine you are using, and called this a plugin. However, this section is for scripts for VX Ace. I am going to assume that you have put this in the wrong forum and move it. If I'm wrong and you are also using Ace, please Report this post and ask for it to be moved back.
Would you please edit your post to give a link to where you got that HUD maker. There are several out there, and people won't want to have to go hunting to find the right one.
