Eheh, as you may know, the translation is not perfect, so I may have some difficulty understanding, but looks good so far. :i-m_so_happy:
Vosk, I've seen this problem too, but I still don't know why it happens, I am using a win32 internal library for that, so it's not my code, it may have to do with some setting I am not aware of.
Try double-clicking any parent folder of your VST plugin folder, at least here it makes them all appear again.
For now, if you need to reset your origin folder, open regedit and locate the
HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\JBridge\jBridgerOriginDir
node.
Delete it and everything should be OK again. Until I can find why this happens it's the best I can do, sorry. :-/
