Updating OSCAM on Alien 2 help!

[zcubed]

Hi All,
I have a Alien 2 working with SPARK and a cline with OSCAM ymodv18-t39 which I appreciate is now an old version. I'm trying to update using the plugin from this site
oscam_y-55.plugin but although the STB says the plugin was successful, I don't see any change in my plugin list and when I connect through the web interface it still shows the old version 39?
I'm sure I must be doing something wrong.
Any help much appreciated
