RMX not working in Glyphs 3

Hello @GeorgSeifert
I updated to Glyphs 3 about a week ago and the RMX tools don’t seems to work, I can’t seem to find why…
I can still find it on the filter menu but when i try to use it glyphs quit.

I’m currently under glyphs 3.0.4 and under 3.9.1 python, (my computer is on Catalina 10.15.7)
The other plugins work fine and the scripts too.

Would you have any solution for the problem ?

There was an update for the RMX-plugins yesterday: RMX not initialized when there is no internent connection - #4 by TimAhrens

thank you @GeorgSeifert !
