Disappointed!

Ive used this app for two years or so to empty the cache and other data hogs. In fairness, I noticed a big difference (much faster) when surfing the web after using this product. However, after the last update, if there was one, (October 2015), the app stopped launching and, when I went to the Koingo website, it said I had to buy Version 5. Forget that. I paid 14.99 the first time and still have the same OS on my Mac so, in my opinion, I dont need the latest version. If I did, it should be an update, not a new app purchase. I deleted the product and wont use any more Koingo apps because this is not a good way to do business.
