Hi All, As title says, latest version of Ultrasurf v13.04 is not working on my Windows 8.1 Update 1 PC. When double clicked, it is running in task manager; but, sites are still blocked. Unable to see even it's window. I tried with running elevated privileges also, same result. I installed all Windows Updates till date. My Windows edition is ProWMC_x64, permanently activated. Please somebody help to get rid out of this. Thank you in advance. SOLUTION: Restart PC
