We have updated the installer package to v1.01 due to a few bug reports from players. There are mostly very small bugs that our test team missed, but there is one bug that could crash the game (albeit the chances of you actually encountering this bug are remote).
If you are already using v1.00 we do not recommend updating as we cannot guarantee saved games will work between versions. If anyone does find it necessary to update and loses their progress as a result please post in the game's forum and I'll get a new save game file to you ASAP.
