Problem running WSR Macros

I just downloaded the WSR Macros program and started it up, created my first macro ("CopyURL" from Brad Trott's book), saved it to the macro folder, signed it, etc., but it didn't work.  I then thought the problem might be the security level, so I tried to right click on the program's icon in the system tray, and it disappeared.  In fact, every time I mouse-over the WSR Macro program's icon in the system tray it vanishes.  When I launch the program, and go to Task Manager, it's not listed as running.  It appears that it may run for an instant, putting the icon in the system tray, but apparently quits immediately.  I restarted the computer, removed and redownloaded and reinstalled the program, but it still doesn't work.

I'm really anxious to get this running, but I'm not sure what else to try.

I'm running Vista SP1 on an HP tx1000...everything else seems to be OK.  Any suggestions would be greatly appreciated.

Yes, the microphone is attached and working.  I sent an e-mail describing the problem to Rob Chambers at Microsoft, and he replied that this is a known problem for some PCs.  He thinks they have a fix, which will be available in the next release.
