Thats the one from JMBSoft? Bad news i'm afraid, it tries to call back to a defunct website to check the serial number (even though you do not need to add a serial anymore, it still calls back) so it no longer works at all.
This is a real shame as it was an incredibly useful piece of kit and i've still yet to find anything half as good to replace it.
If anyone has worked out a patch or a workaround please let me know too.
