I have this problem for a while, have to reinstall one of plugins every time before start to work, and it’s just annoying me.
Plugin .rbz files are stored at D:/, and path name is English, so should not be path’s problem.
The wired thing is, after reinstall, all plugins are back, I have to pull plugins to top bar one by one,
only Vray not effected.
Already checked other post, my plugins are least.
