Does not receive the confirmation e-mail!

Hello, 

I recently downloaded the DraftSigth, free version (the last one by September.01.17) to my Mac. When it asked me to register and when I fill all the info to get the confirmation e-mail, I click "continue" and the window disappear  and I do not get the confirmation e-mail.

Can you help me to resolve the problem, please?

 

Here is the my laptop system info:

Model Name: MacBook Pro

Model Identifier: MacBookPro14,1

Processor Name: Intel Core i5

Processor Speed: 2.3 GHz

Number of Processors: 1

Memory: 8 GB

 

Also, I am in the US. I am not sure if it matters. The reason I am writing here is because on the first window it asks the location. So, if it is related to the location, you have an idea. 

 

Thanks.
