Hello, looks like you are a bit confused with Mockplus Classic and Mockplus Cloud. 

• Mockplus Classic is a desktop prototyping tool that can help you and your team to translate ideas into live website or mobile prototypes in minutes. It focuses on the prototyping process only. 
• Mockplus Cloud is a one-stop online product design platform that connects your entire design workflow from prototyping to design handoff. It helps you bring all designers, developers, product managers, clients and other related design participants to the same project. 

So, they are different. 

By the way, you cannot use the desktop app with Mockplus Cloud yet. but, it is easy to import the projects of the desktop app into Mockplus Cloud under the "Prototype" mode. 

If you really think Mockplus Cloud is helpful and want to convert the license from Classic to Cloud, please contact support@jongde.com with your order number, purchase invoice and email account offered. 

We'll do the conversion for you as soon as possible.

I'm keen to know this too.  I just signedup to cloud the otherday and made a few mistakes and found it easier to use the classic app.  However, I realised the app is a trial only.  

I'm happy to stick to the free cloud but cant see the edit function from a uploaded file.
