Cubik Studio

My cubik studio only works when https://cubik.studio is online, but when this site is down, as it did yesterday, it hurts my work, because I was almost all day without work.
After all, was this editor programmed to work online? I can not use when it is without internet? Can't use when the site is offline?
How to use a paid program without internet? It is my work tool.

"Asks to register, it has already been registered. Correct password, but the publisher does not want to work, because the site Cubik.Studio is offline ......."

There are many offline working tools, such as Scirra's Construct 3 case. Works great offline.

The purchase page does state the program requires to be online at launch:

Internet connection required at launch for the software to operate correctly

I'm sorry you were inconvenienced, however the website is rarely down. The recent downtime was a very rare occurrence.

I see, thank you very much for the feedback.

BUT DO I DENOVE THE SAME PROBLEM ?! OUT OF DENOVO AIR ?! THAT HARM MY JOB A LOT; I'm wasting time. NEED TO WORK!! WHAT IS THE OPTION FOR OFFLINE ??
