"Invalid Email"

[finalchild]

I executed Cubik Studio, and I was prompted to enter my email and serial key.
I entered '<username>@ourmc.space' but the program said the email was invalid.
I was able to change the email information from the website(to <username>@naver.com) and log in.

The program doesn't accept emails with long domains('space' is 5 characters long), which is inconvenient. I wish this issue to be fixed.
