Oh, that's a blow.
I found I was able to reproduce the issue, and I found a way to fix it with this update. At least it's fixed on my system. There must be a further problem of some sort.
I'd like to at least check that this install worked correctly - any chance you could Console.app - when TotalSpaces2 starts it should say something like this:
26/04/14 21:54:46,356 Dock: [TotalSpaces] FastSwitch2 (c) 2011-2014 Switchstep is association with BinaryAge
26/04/14 21:54:46,356 Dock: [TotalSpaces] FastSwitch2 is being initialized
26/04/14 21:54:46,357 Dock: [TotalSpaces] Mavericks detected
26/04/14 21:54:46,371 Dock: [TotalSpaces] FastSwitch2 ready v2.1.8
This would confirm that the correct version is being installed.
