For Mac users: 1.06 is an Intel-processor only build. See our previous update- we are no longer supporting PowerPC-based Macs. If you have a PowerPC Mac, we obviously recommend that you do not upgrade. For Linux users: 1.06 is compiled with the latest libraries on Ubuntu 10.04. This might make the game incompatible with your system. Consider trying the demo before you request a new download link.
Links for the demo can be found in the downloads section of our website. If you need a new full version, please email us your purchase information (order number works best!) and we can activate a new download link for you.
We are sending these updates out to our distributors (Steam, Direct2Drive, Impulse, etc.) tonight. They will have their versions updated in a few days if you bought your copy through them.
