Stellarium : Lost the configure Solar System Editor (Solved)

[Malpi12]

Help ! While updating the asteroid database ( I had just updated ok to include 7482 (1994PC1) ) but then I have messed something up  
In Plugins, highlighting the SSE brings up the configuration window but  the configure button is not working (remains white)
I have ticked the load at startup box and restarted as per FAQ1746
https://answers.launchpad.net/stellarium/+faq/1746
but still no joy

Stellarium v 0.18.0 Windows 7 64bit
Any ideas where to start looking please

(yes 18 is very old but so is my computer ! and that was the last version that worked for me, something to do with graphics card and/or OpenGL)

Thanks.

Solved.

Found the Stellarium archive of versions and re-installed 0.18.0
All now good (until I do again what I did before to corrupt it !!!  )

Now that I have asteroid 1994 PC1 updated (again!) , , , all we need is a clear sky !
