The data present in your database is newer than the version of JIRA you are trying to startup.

Hi, 

I recently did a local install of jirra, but I installed a version newer than what my license supports, so I removed that version and installed the current version. 

Now im getting the following error and don't know how to remove the old database?

 Your help will be appreciated.

If this is an experimental purpose, drop the database and recreate it again OR remove all tables from the database. If you're using mysql, then goto mysql> drop database <databasename> and then create the new one. The build number value stored in the database that is causing this.
