Check what version of JRE (Java Runtime Environment) you have. If you don't have the officially supported version (eg 1.6.0_24) as documented here this may be the cause of your problem:

Later versions can cause certain SAS components to fail. We have used 1.6.0_24 and 1.6.0_32 successfully but have had problem with later versions.
If that doesn't help try following the advice here:

Good luck!
