This seems to be a bug inside the RPG Maker engine itself that occurs on some very specific computer setups. There isn't much I can do at the moment outside of contacting the developers of RPG Maker itself. It looks like the issue is in one of the default RPG Maker scripts which may or may not be conflicting with something (seems to happen to certain people running Windows 8.1 so far).
I do have an experimental fix that may help, but this hasn't been tested enough to be officially released yet. If you'd like to try it, please download the file here
http://www.darkgaiastudios.com/Scripts.rvdata2 and copy it into your C:/Games/Heroes of Legionwood/Data folder, overwriting the Scripts.rvdata file that is already there. This file removes the default RPG Maker script that I believe may be the issue.
If you still continue to have the error after trying this fix, please contact BMT Micro for a refund of your purchase.
