Hi, thanks again for the return. With my issue I was not even able to connect to there 2 servers to get into there site. I tried 2 different comps also, to no avail. During this time I got sick and had to put every thing on the back burner but now I am on track again. I bought a new dongle also at the time but now I will install and see what will happen. I remember now the responses I received was it was having issues with win10 and the dongle drivers.all licensed keys have drivers. On there site at the time they only showed win7 as there operating platform. Even though the dongle package shows it will work on win10 the vender said there was problems with the drivers as he had others that were having issues. I’m not sure if ZXW has updated it drivers to include win10 and again it would matter what win10 platform build you are running.try updating win drivers manually.if they have not updated this could definitely be an issue.the functions can be unstable and inconsistent.So before you renew maybe address the driver issues ask zxw if they have any updates for win10 drivers or any windows versions. I will be installing my new key in about 1week , I wil inform you of the outcome.In all seriousness the the driver issues could be the root problem. It will be great for everyone to get this figured out. Till then.

Does make sense but first thing they did was checking the serial numbers and confirmed dongels are good…. I’m directly in touch with “ZXW客服“ over QQ and this is what he wrote me:

——————————————————————————

****I suggest that you find a dongles that you can use to test if there is a dongle that can be opened in your network environment.****

****In general, you can buy a new dongle test****

****But I’m worried that the dongle isn’t bad, and that the same problem applies when you buy a new dongle.****

**** I have no way to solve this problem ****

——————————————————————————

However I’m using other softwares already but will give it a try by renewing the license to see whether it works or not, I know many colleagues experienced this issue and given up… so it would be good to know what causes this problem after all…

Thanks for your advice, Yes i did refresh the menu too but nothing happened.

Thanks for the return. This could be a long shot thought, could it be the licence serial # is no longer good. There might be a time frame where a set of numbers are good for, the dongles you got are out dated from the vender you bought them from after that you need to renew the license ,even though they said the numbers are good they might have not been up front telling you, you need to renew? I know this sounds lame but it could be as simple as that. You have trouble shot every scenario and a still no go result, I’m leaning towards the serial #’s are out dated. You might have to look for another program for the schematics there are other good ones out there or bite the bullet and try to renew one of the numbers you have. Not many options left for you.

Did you try refreshing the menu?

Thanks for the link but it’s actually communicating but doesn’t load the schematics… I disabled anti virus, firewall… even the router firewall… also tried on several computers with different ISPs… furthermore I used VPN and set location to be HK, UK, US, Mexico to see wether ports are intercepted or not (also checked the IP before each attempt to make sure i‘m picking those countries local IPs) but nothing changed and still not loading the schematics in the menu, even after hours….. need to mention my dongles are genuine and the goes from Ztools checked the serial numbers…
