Unfortunately, I cannot assist with finding the password to unzip and install HBV light 2.0. It is best to contact the developers or check the program's documentation for information on obtaining the password. To open a new catchment and connect and add data, you would need to refer to the program's user guide or documentation for specific instructions. As for alternative and more recent versions of the software, it is recommended to visit the official website or relevant software forums to explore available options and updates.
