TW: Startup issues TXM for Mac OS X and Windows 64-Bit

Who: TW
I’m new to TXM and the list, so apologies if this query has already been addressed before. I have installed TXM onto both Mac OS 10.9 and Windows 64 bit operating systems (wanted to try it out on both), and have been successful with neither. Both are running Java 7 and Eclipse 64 bit. But I can’t start up either one, and don’t get any error messages, so am not sure where to start to diagnose the problem. Any suggestions?
