Thx Varsi - it worked well so it must have been a version issue. FYI - I play Kerbal as my man cave time after work. I haven't upgraded beyond V23 because I am a poor spaceship designer and my ships are not robust. So when I port my super huge fuel tanker with 21 tanks (it was empty when it reached orbit) to a newer version - it immediately develops a oscillation that rapidly leads to its self destruction. But I am having fun

Thx for prompt response - i'll give it a go. Any idea of a source?

Hi Hopefully someone can help as i am at my wits end. In brief i am running kerbal V23 and after being unable to dock my craft, I downloaded Docking Port Alignment Indicator However it doesnt seem to want to run. The following is my screen once i have select the target docking port http://www.tiikoni.com/tis/view/?id=16df035 And these are my Kerbal Files http://www.tiikoni.com/tis/view/?id=aa2dd1e Any thoughts?
