I have a community created add-on for Hero Lab for the ARG play test rules. This add-one will allow you to create races without having to use the HL Editor. The creation rules follow the ARG play test rules exactly.
For the full details please see the ARG playtest add-on post over at the Hero Lab forums. The post includes a step by step guide for the install which is very easy to do.
This is created by the community for the community so it is 100% free. The add-on *should* not require any data sets past CORE but that is hard for me to test so I am not 100% sure actually.
Thanks
