Futuremark has released a hot fix for 3DMark03/05/06 and PCMark05 which should bring the benchmarks up to date with new graphics cards and processors. The problem is that none of the benchmarks behave properly unless they detect the hardware in the system correctly and as a result some tests might not run properly or at all.
There was a workaround for this, but it meant that you couldn't post the results on the Futuremark website as the results couldn't be verified. The download only consists of three files and it works with all four benchmarks. A new version of 3DMark 06 will be made available with the hot fix included.
