When I Downloaded Technic Launcher, It was fine. One day I opened it and it was having issues. My First thought was to delete then redownload it, as I has done previously. I downloaded it and when I opened it it said: "Windows SmartScreen found that this file can potentially harm your computer." I realized it was because it had an unknown publisher, so i hit "run anyways." It never opened and it still won't. Please Respond ASAP, because I play with friends, and skype, often.
