Why can't I open my GoldenDict?

Yesterday, I installed GoldenDict in my Windows XP Professional (version 2002, Service Pack 3) system. It was working OK.
Then I started to download Babylon dictionaries. After downloading quite a few, I rescanned them.
Then, GoldenDict crashed never to open again.
I've tried the basics: restarting the machine, uninstalling and reinstalling the software, cleaning the register, but to no avail.
There is no Error message, or something.
When I click in the GoldenDict icon, the software simply doesn't open. It doesn't even show up in the Task Manager.
Any ideas?
