[NTG-context] Attempt to call a nil value

Hello list, since one of the last beta updates (now I have 2018.09.01) I can't use ConTeXt on my Win 10 32bit tablet anymore. I can't make PDFs because I get an error message. In fact, with CTX in my system path of course, even when I type the following into my command prompt, I get the same error: mtxrun --script context ./context.lua:11: attempt to call a nil value (method 'add_rule') This could have to do with the last adaption to Textadept 10. On my Win 10 x64 PC there is no problem. Any clues? Cheers and thanks, Lars.
