Alright, same error has arrived! I am familiar about this issue, and ultimately the solve for my problem was downloading earlier patch ( way down several patches ).
...So, after an patch update, no VST-plugins are found from scan. Where they are exactly? I did reset shop and all other plausible things which would cause it, but this time I am completely out of chances. Of course, I have to be aware that people might not remember at all, so I am willing to follow a step-by-step. But...
Possible to get an earlier patch, or do we this time have a proper answer? I even did place plugins on desktop and scanned there, still no visible to interact, downloaded or not.
EDIT: I just restart computer, if that helps.
EDIT:2 Restarting PC didn't help. I even did download them back, that didn't help. This time I am really out of options.
EDIT3: Back to step earlier version: All is fine!
