Could not connect to database

I am a beginner to cuba studio and my work is to generate a report using reporting tools add-on and I’m facing an issue in the very first step. After testing the connection successfully, and loading tables from the database the cuba platform gets hanged.

Can you show the screenshot of what you were doing?

Please attach idea.log file. You can find it using main menu: Help -> Show Log in Explorer
Also please attach screenshot with expanded Run toolbar after Update Database was called. (Left bottom corner on the screenshot provided) So we can see the error message that is hidden on the image above.
“Exception when mark sql scrip…”
