People on older CPUs should really do the hex fix. I haven't had a single crash since I made that change. I have experienced other bugs, but no crashes.
The fix for 1.04 is exactly the same as for 1.02, just using the newer 1.04 .exe file.
That fix got me going but after doing the update, I get consistent crashing immediately. I noted that the update did change the .exe and I re-entered the hex fix, but the immediate crashing continues.
