Lectora menu under Vista not responding

Where do I find the patch to fix the Lectora 2007 working in the windows vista platform?I am unable to click anything on the menu bar in Lectora. It just immediately states "not responding". I've uninstalled/reinstalled Lectora, deleted temporary files, made sure Lectora was included within the "trusted sites" in my firewall.I'm a graduate student trying to learn Lectora and I am beyond flustered.
