I am having the exact same issues here in the US in PA. Eastern Time Zone. No matter what I set the time and date too I can get no Trial Code for it has this error:
Sorry, an error (403) occurred registering USB Flash GUID (###################)
The error is: Your time/date is incorrect, please update it or enable NTP.
I have tried NTP and that does not work. I then set the time in the Bios to match. Supposedly you are allowed a five minute separation, but I have them both exact down to the seconds. Nothing, No email comes and I can not do anything with this thing. Frustrating indeed!!! I built my NAS and it is sitting next to me hard wired LAN line. I am accessing the server software page from my windows 10 based system on WiFi. Do you think that may be the reason for the separation of time? I am unsure why I am unable to get through to get a Trial Key and support from Lime-Tech is like looking for a sky hook in a scavenger hunt. I found a contact for help and received two emails asking for curtain information out of the Page Map under tools. I sent them what they asked for and never heard from them again. I am wondering if I should just purchase the darn key but I am worried that if I can not use it, I will waist 50 dollars. Any ideas anyone can provide would be fantastic. Please speak to me like a 3 year old and guide me through this if your able. I am not very DOS friendly at all.
