The issue has been solved in COZYROC SSIS+ build 2.1.100.3226.
The workaround, provided below, should be used only for earlier COZYROC SSIS+ versions.
What you need to do to make your connection work is to go to the Properties window to set the password rather than setting the password directly through the component. There seems to be an error in the way it processes semicolons in the password when the password is entered directly using the connection component.
