Installed Categories months ago. Had my apps all neatly in 11 folders but wanted icon options and found Categories V1 Icons which is labeled an add-on pack. I still have my folders, but when I launch Categories, I have a blank screen, it no longer sees all of my existing folders. I assume I can create new folders and put my apps in these, but then I have two sets of folders... and no way to delete the old folders. Any ideas?
