After I downloaded the Turbine Download Manager, I let it run overnight. I was happy when I woke up and the "Play" button was displayed, so I clicked it. The Download Manager minimized, my mouse cursor blinked the hourglass twice, then nothing. No entries in the event log. No error message.

I tried running all the non-uninstall executables, and they all have the same result (except for dndclient.exe that complained about not passing a command line parameter). I saw no log files in the directory (except the dndclient log about the parameter).

Windows Vista Ultimate 32bit
AMD Phenom 9500 Quadcore
4GB RAM
ATI HD2600XT Video Card

I'll take any suggestions.
