[PROBLEM] Update questions and XBIAN config problems

[IriDium]

I think you are out of luck.

There used to be a route from Alpha 5 to RC1 and then from RC1 to RC2 but I think that route is no longer an issue.

Unless you have made major changes, it would be best to start again from afresh. This is sometimes a good idea with any operating system - clears out any dross and unused files/folders.

I would make a backup first - use Win32diskimager to read the SD card to a img file on your PC.
Use XBMC addon xbmc backup to create a backup of your home directory.
System -> Audo - export video library.

This will mean that "Nothing" is lost - although it may not be easy to restore them.

The snapshot feature was implemented in Beta 1 (I believe).

So bite the bullet and go for a fresh install. (IMHO)
