Cannot start 5.1

I have installed 5.1 with Tomcat 7.0, Java 1.7 and Postgresql 9.2, on Windows 7 x64.

I think I have made all the configutarions correctly, but cannot start.

The first lines of Pentaho.log file:
2014-07-29 14:33:53,901 ERROR [org.pentaho.platform.util.logging.Logger] Error: Pentaho

Anyone could help me? I've not found anything about these errors.

Excuse me for my bad english.
