For Clerics, this would simply be a case of owning a printed copy of the player's handbook :-)

What do I have to do to get the last 3 chapters loaded? I paid for this...

Finally got it to load. I re-installed 2 more times, including a reboot.

To get the updates, you need to use the "Find Updates" option within HL to download the latest version. The button should be highlighted indicating there are new updates available.

After the files have been updated, then the new data should be available (assuming that the new material is included in all your purchases).

Any ETA when 14.20 will be available? :) Still a lot little bugs to squish. :)

Hopefully soon.

In general we can't really give estimates on a lot of things, as occasionally issues crop up that cause delays, or priorities get shuffled, so we don't want to cause false expectations. That said, it's going to be a while on this on because we've got some very large projects in the works that need to get out first. We've absolutely not forgotten or abandoned support for PF1 though. Bugs still get logged, we just need a good opportunity to tackle them.

Would you be willing to take on volunteer's to help fix some of them?

It's less a case of willing and more of having to address certain complexities with that. That would require access to edit non-publicly editable files and to where we log the tasks, so probably not. In all likelihood though, we'd probably look to have contractors do more entry of materials, freeing us (probably me lol) up to tackle bugs. That'd be the simpler approach. Currently though, we do need to finish our larger projects before we can address it in any manner.

*Don't really quote me on this, as situations change and maybe we can make that work in the future, but at present that's the situation as I understand it

It's really unfortunate that you're team won't be willing to allow for volunteers to work on the bugs for HLC. I'm sure there would be a couple of people that you could vet, sign non-disclosure agreements, and perform the work needed. Oh wait, wouldn't that be an unpaid contractor? :-/ It's been 6 months since we since an update to this software, and yet keep saying you haven't abandoned it....
