Just saw that people were having issues with playing XCVB to completion. Turns out that it wasn't possible to get past the first green level. A new update to fix this is coming.
Apologies to all those affected by this.
A link to the updated version before desura approves it can be found here: Mediafire.com
Just open up the zip and install. It should overwrite the old XCVB install and fix the issue. You will however have to start a new game.
If you've any issues tweet at me. I'll get back to you as soon as possible.
