I looked in my template folder for Hero Designer v3, and I have four templates. I am unsure if any of these came with the HD, but maybe one or more did. The ones I have are:
Combat Record Beta Test (HTML) (gbsbetatesthtml.hcr) created by Geoff Speare, version 1 (9/15/03)
HTML Combat Record (CombatRecordHTML.hcr) created by Geoff Speare, version 2.0a (11/22/03)
RTF - Combat Record Sheet Option C (RPM_CombatRecordSheetC.hrc) created by Robert Miller, version 1.1 (05/05/2006)
RTF Combat Record (CombatRecordRTF.hcr) created by Geoff Speare, version 2.0a (11/22/03)
I'm not sure where I got all of these, buy maybe you can do a search in the Downloads area of this site to see if these exist there.
