I have no idea what caused it, but for some reason the game no longer works on my Vista. I have a number of copies of both the 0.9.8.1 version and 0.9.9. version kicking around on my computer in various places and, parts of most of them, incredible as it might sound, have simply vanished. Only one of my copies of 0.9.8.1 still has all its files and its exe simply will not run.
As for the others, in every single one the exe has vanished. In one copy of 0.9.9, only the exe has vanished, while in another, the exe, the batch file, .dll, .dat and .ini files have all vanished.
There's no rhyme or reason to any of it either. The 0.9.9 that has only seen its exe vanish is the 0.9.9 version I did most of my 0.9.9 games on, while a completely fresh and untouched copy of 0.9.8.1 that I only used for the graphical settings on has also seen only its exe vanish, while a second version of 0.9.9. I did play a few games on is the one that's had all the stuff I described in the previous paragraph disappear.
I tried downloading and unpacking a fresh copy of 0.9.9, but its exe wouldn't run either. Aditionally, unpacking my old copy also gave me a complete copy (but still with non-functional exe), but then the exe disappeared from that copy as well...
I have to wonder, what the chuffing Hell is going on?
