Event Log Analyzer cannot start

Hi everyone,
the evaluation period of my Event Log Analyzer installation was expired. The program automatically switch to free edition and I was able to cllect logs from 5 hosts. After a server reboot the service starts normally but if I connect to the web client I received the "page unavailable" message. If I launch the run.bat script I've got the option to insert the path of the license file (I don't have a license file for the free edition...) and the program won't start. The Windows Event Viewer reports this message "WARNING - System.in can not be used when the JVM is being controlled by the Java Service Wrapper. Calls will block indefinitely."
How can I start the program??
Thank you very much.
