Simonneu,

There are two required files: webfront.zip and Xeams.jar. You will run into above problem if the webfront.zip was successfully patched but not Xeams.jar. Try downloading them manually from http://xeams.com/ManuallyPatching.htm and try patching. If the web page is not comming up, shutdown the service and use the manually method specified towards the end of http://xeams.com/ts-auto-update.htm (the command that ends with EngineStarter). Make sure Xeams is NOT running when you issue that command.
