please help.

Hi,
since we do not have a CentOS installation on one of our Linux computers, I can't really reproduce your error. We have the current SuSe version installed and it runs just fine. But I could make some guesses.
- Try to install an older java 1.6. We had some problems before with the newest update, because they have changed some important behaviors. This problemes occured with the windows version, but probably its worth a try.
- The second thing is, that the classpath seems not to be set correctly since it can't find the operators classes. Did you use the start scripts? Does it work if you start the gui?
- The cryptography engine seems to work in a different way than on other installations or suffers from the same error as the operators.
If you find a solution or eliminated some of the possible sources of error I would appritiate it, if you could tell us.

Greetings,
  Sebastian
