get Stardock Central
- register WB in it and use it to download/install the most current.
all your files (except the 2 I mentioned are for 5.1.009 release.
The 2 I mentioned should show as:
Wbload.exe 2006/03/13 17:54:14
Tray.dll 2006/04/13 17:29:23
If they don't after using SDC, I suggest an uninstall, reboot and retry via SDC.
