Fredo6 not working

[Panuwat Boonthongtho]

Joint push-pull user interface is grey. Fredocorner and Thrupaint don't work at all. The problems have occasionally been occurring for a while. Please, anyone, tell me how to fix it.

you might need to update fredo library files via the sketchucation extensionstore plugin
