Has anyone had problems with this upgrade to 11.0? I have been working with 10 projects or so with my Lenovo X1 Carbon laptop running Win 7 for years now. I just installed Ver 11.0, keeping my older versions available. I opened one of my project files and upgraded it to 11.0 then tried "Find Main Repeater" and it did, I tried to transfer to the repeater and it failed. I called tech and was directed to go to Advanced Settings in find main repeater screen and change it to Multicast. At this point it would not find main repeater anymore. Now I go back to the ver 10.2 and open the file and it finds the main repeater, try to transfer to it and it fails. I have not been able to connect with any of my main repeaters since. I sent the 11.0 file into tech and they said they were able to connect to the repeater with the file I exported. They said it was my computer that is the problem. I run Symantec Endpoint protection and it gets disabled before attempting any connection. I turn off Windows Firewall in Advanced Security for domain profile, private profile and public profile. I have connected directly to a main repeater and it still won't connect, wired into the network and NG. I updated my Windows with all available updates and drivers, updated Bios and all Lenovo updates after this issue started and no change. Does anyone know what could be causing this. I need to install the devices at a project but I cannot transfer to any main repeaters anymore. I can still transfer to HAI OmniPro II, Vantage Infusion controllers, RTI control processors but cannot transfer to Lutron main repeaters.
