1.1: A user is complaining that his download speeds are low.
Hi 
Thanks for letting us know about the download problem.
Unfortunately, download speed is mainly dependent on local conditions and the type of internet connection you have. If for some reason there is high local usage either region, city, or local to your ISP then speeds can vary.
We use cloud data centre services  (CloudFlare) with tens of locations across the world to provide our users with the best locally accessible bandwidth. The ###NUMBER### servers in your country are operational. 
Please check that your PC is also not busy doing other download or disk-based tasks.  Otherwise, the Download Manager can be paused (or stopped if needed) and this enables you to keep the download until you can get access to a steadier/faster internet connection. 
Let us know if you still have the problem later on.  And let us know if there's anything else we can help with.
Hi 
Thanks for reaching out. 
Sorry to hear you are experiencing slow download speeds.
Unfortunately, download speed is mainly dependent on local conditions and the type of internet connection you have. If for some reason there is high local usage either region, city, or local to your ISP then speeds can vary. If you are running other apps (anything that constantly uses data) while downloading, they might also be taking most of the bandwidth.
You can see the maximum speed of your network at the link below.
There are no download speed restrictions for the Lumion files. We use cloud data center services with tens of locations across the world to provide our users with the best locally accessible bandwidth. The servers in your vicinity are operational. 
Please check that your PC is also not busy doing other download or disk-based tasks. Otherwise, the Download Manager can be paused or stopped if needed, and this enables you to keep the download progress until you can get access to a steadier/faster internet connection. Keep an eye on the speed and it should hopefully improve over time.
Please also follow the instructions in the link below to make sure that nothing is interfering with the downloader.
Let us know how you get on with the download.
