As pointed out already, sadly no. Which sucks bigtime because Steam auto-upgrades your program by default (and INSISTS that you upgrade before you launch) so it's really really easy to find yourself up the proverbial without a paddle. I had kinda shelved KSP for a few months waiting for everything to catch up to 1.0 in the, now I see, misguided hope things would stabilise, but the minor number upgrades like .0.1, .0.2, .0.3 and .0.4 are anything but.The upshot of which has been that I now want to try it, find the default game boring as hell, and now can't play the damn thing because there is no 'legal' way to lay my sticky fingers on 1.0.2 - despite the fact that I'm a paying customer. Damn, I should have half-inched it in the first place. Support like this doesn't deserve my custom However, on the other hand, I suppose it's technically impossible for me to pirate something I already own.... Still, very irritating.
