I Suppose there was some problem which you might have not noticed while uninstalling the application.
If this is a
test environment or development environment, and if you are ready to forgo all the configurations that you had made earlier, there is a simple way to get along, just recreate the admin database, afresh, and start with creating of resources and install the application.
in bin/admin.config, there is a flag which indicates to recreate the admin database, this option can be used and recreate the database.
If this is a production environment or you have other applications installed which you dont want to loose, then it is better you analyse what the problem is.
Hope this helps solve your problem.
