What am i supposed to do when this message pops up during a vst scan, it open windows explorer and stopes the scan " Select Waves 9.7 SG Studio Modules Folder". I know this refers to Sound Grid, ( part of a bundle I got once) but not really sure how to even use it??! So I hit cancel and the scan proceeds. Choosing folder I think might be correct does nothing.

Try loading the plugin into a project and see if it raises the same dialog, in which case it might give you a better idea of what it's asking.
