I haven't worked on the tools for years now. I had started making a brand new version but with the coming of Frosty, there was no need for it.
I have not worked on anything Dragon Age related in over a year and I will not ever again.
However, the tools are still available in the official discord server : https://discord.gg/Ynr6knP
Join it. There's tons of good people on there who can help you troubleshoot issues and get you started on modding DAI.
Cheers and adios!
