Pactimo review for Smart Product Filter & Search

Great app...until it suddenly froze up on when I tried to reindex my site on BLACK FRIDAY WEEKEND! Removing it broke my entire site. From what I can tell, they changed the way the app worked like the day before Black Friday. How stupid is that? I really loved this app, but now I am so frustrated I could cry. We are losing sales and everything on my site is broken and none of the links I relied on with the app filtering are working.
