Multiple generations are not booting?

[mprowe]

WoooHoooo..... Its working again!

So, what's changed?
If I download the image file from SourceForge its called "XBian_2015.05.16_imx6.img.gz"
But if I use the Xbian Installer (still v.1.21) its called "XBian_Stable_rpi.img.gz"
Are they they the same? Why the change from a (reasonably) understandable naming convention?
How has the Xbian Installer stopped listing all the images from its working directory and now only lists: Stable,
2015.04.04 & 2015.03.31?

And lastly, how can I see what Xbian version is in use from the Confluence GUI, now that this information is missing from System | Settings?
