Analyzer on Ubuntu

I've installed the EventLog Analyzer on an Ubuntu 6.06 server version, and it installs fine. However when I go to start I get the following error message (many at java.util.... lines have been deleted). With an errord code 469 Invalid license file. Anyone have an idea?

Error Message below-------------------------
java.io.IOException: Couldn't get lock for /usr/local/AdventNet/ME/EventLog/server/default/log/serverout%g.txt

Thanks...rich
