First of all, sorry for my bad English, my PC is running Win 10 Pro 64Bit with Hyper-V enabled. Yesterday my ESS 8 updates to ESS 9 and ESS told my to renew my Activation. I got a 4 PC-License with expiration date 04/2018. I requestet a license key with my Username and Password and gets my key, but ESS told my there's a problem with my activation. Next Problem, the Firewall didn't starts. I uninstall ESS and deleted all Files of the Program on my PC and in my Registry and installed it new, but still got the same problems.
