Check control panel to see how many Java JRE you have in your system and what is the latest version? Try to stick to JRE 1.4.2 as we have not tested with JRE beyond 1.5.0.
Also try to re-install TRiLOGI after you have fixed your JRE. This eliminate potential problem caused by corrupted TL61.jar file (I am not sure why and how it could be corrupted, but just in case).
