Haven't actually been able to register and play online yet, but are the versions different or so? (this was the DRM-free Windows version)
KAG classic "which is the second one you downloaded I think" is very different from the beta version. It is the older version of the game with not nearly as much content as the current beta has now. KAG classic does have zombie fortress mode which is just epic. I highly suggest downloading both versions of the game since they are so different.
I'm not sure what it is but the version I have now, after logging in, is different from the one this morning in demo(?). Glitches appear to be gone as added bonus
Will keep both versions for now, Zombies are an overdone and silly theme, but heck another mode to try? Yes, please. Hopefully the Desura version will be fixed so I'll only have 2 installs of the game.
