RealVNC Error Since Updating to OS X Lion

Since the upgrade to Lion I have had no problems except for this one. I have a popup error message that shows the logo for RealVNC and says "Mac OS10.3.9 is the minimum version required!". I can click the OK button which is the only button but it immediately pops back up on the screen. It appears to be related to the VNCServer process that's running when I view the Activity Monitor. Has anyone else had this problem or have any suggestions for getting rid of it? Thanks!
