The problem when deploying using this tool may be related to the fact that not everything is correctly deployed. Try including all files that are part of the project and the bin folder containing dlls, as well as configuration files located under ~/App_Data/Sitefinity/Configuration. Then set the web deployment tool to include all files part of the project.
However I would suggest to push your files using a FTP or directly copying them to the server ( for the codebase ). For the database you can simply backup and restore it to the production / staging server, using the SQL server built - in tools. By deploying Sitefinity manually you will be in better control of your files and process as a whole.
All the best,
