BeMeApps: Sales Pop Total

I installed this app and it looked great but keep having a pop up on my website I didn't like and no one would reply to my requests to remove it. I sent three. But the reason I have actually uninstalled it is because after I installed it I wasn't able to add things to my cart anymore. It kept saying error. I spoke to a Shopify expert who advised it was from this App. After I uninstalled it, it was fixed.
