If you never added any user files you probably have to update your default Configure Hero options. They did some pretty major changes with the AP's, APG, etc.
So open Hero Lab and configure your options the way you like them. Then save them as defaults.
Then open each character you want to work on that you previously saved. Select Character then Configure Hero then click on an option to get the full window to pop up. Then select "Use Default" and OK. Then save the character and it will have updated your character to the new settings and patch.
If you do not want a set default, just load each character and verify the configure hero options are how you want them then save the character.
That should get you back on track. If you add new user files in the future you will have to set your "Configure Hero" options to accept those changes by checking the little box.
That Cleared it, Thanks
