Upgrading from Neo4j 2.1.7 to 2.2.0

I was using Neo4j 2.1.7 without any problems. Beside running Cypher queries in the web client provided by Neo4j, I also played with the Java API in a Maven project where I created some nodes and relationships. All worked fine.
My problems began when I decided to upgrade to version 2.2.0. First, I unistalled the older version, and installed the newer one which is 2.2.0. I started the server: Starting the server

I tried to run a simple query and got 'Unknown Error': Performing a simple query

At first I thought that the database located at C:\Users\AugustinUser\Documents\Neo4j\default.graphdb was from the previous version, so I deleted it and created a new one that would comply with version 2.2.0. But I get the same error. Need some help. Thank you!

To upgrade your existing data, make a backup and then. Enable allow_store_upgrade=true in the neo4j.properties file (Under Options)

Shift+Reload helps with the browser.

I had similar problem after upgrading too. Try clear cache of your browser. Push CTRL + F5.
