Hello Eric, thank you very much for your help.
I deleted addons/data/jd in my j64-806 folder. I am using a Mac and don’t use Pacman to install software. So, I started JQT, opened the Tools > Package Manager and installed JD, version 4.4.60. Package Manager says Installing 1 package of size 280 KB Downloading data/jd... Installing data/jd... Done. And then load 'jd‘ gives the error message again !!! Jd key: non-commercial use only! !!! Jd key: invalid |assertion failure: assert | assert 0[echo invalidkey Could you give me a hint to narrow the error cause?
