I have a couple of questions about KIS MP1. 1) do you have to uninstall release version before installing this version? 2) do you have to use the best testing key or will my present key activate it? 3) how does it compare to the present release version? 4) are there any major pro's or con's for or against installing beta build? Feel free to add whatever thoughts or questions you think may be of importance to this thread. Please only people who have actually tested KIS MP1 and not people who dont know what they are talking about!!!
