Basically the problem is that Rapise clicks on an <a> element that is reported to have 0 size (according to IE), it clicks on the border of the link which is actually inactive. In this case, we instead should try to click on the 1st element inside the <a> element which is a <div>

The default XPATH recorded by Rapise points to <a> element:
 

/html/body/div[@id='header']/div[@id='header-inner']/div[@id='header-nav']/a[3]


And we need to tweak it to point to <div> element right inside of it:
 

/html/body/div[@id='header']/div[@id='header-inner']/div[@id='header-nav']/a[3]/div


After that the script will work as recorded.
