[Plugin: Event Calendar 3] Wrong links to posts in event calendar widget

Hi!
When I add events via event editor in the Edit Post page Event Calendar 3 has wrong links to posts in the event calendar widget; they look like e.g, “www.mysite.com/wp/?m=20120404&cat=34” instead of “www.mysite.com/wp/?p=463”. Can anyone please advise what I can do to fix this? Thank you!
