Trying to find additional third party info
 

I have gotten a new laptop and transferred my licence to the new one but all the extra classes and races that i had are no longer there and I'm trying to find where in the forum I found the initial file for them.

If you're talking about the community pack the instructions are on the top sticky post in this forum. Click Here.

If you've done that, you might want to make sure you have the sources enabled, you can do this when you first start Hero Lab and choose 5e or on any character you can hit Ctrl+K or choose Configure Hero from the Character menu.
