hwinterface.sys causing preview map not to work

I hope I have placed this in the right section.

I have just upgraded my hardware to AMD phenom AM2+ processor (on windows vista 64 bit) when I now go to select preview map after building the map, the windows comes up as if it is about to run the program then closes, with no visible error on screen.

I have looked in the windows logs under system logs and the following error appears in there:

\SystemRoot\SysWow64\Drivers\hwinterface.sys has been blocked from loading due to incompatibility with this system. Please contact your software vendor for a compatible version of the driver.

I have taken off the User Account Control on vista. Everything is running as administrator.

I am just wondering if anyone else has had this problem or a similar problem? Any help would be appreciated.

I don't know the "hwinterface.sys", so I can't comment on that particular problem. However when you report a bug here it would be good to know which version you are using, and also the content of the acklog.txt when you encounter such a problem and start with -diag. The acklog.txt also gives you a hint when something goes wrong. Maybe its not related to the "hwinterface.sys" but to something simple, like an empty level or a wrong camera position.

I installed Vista SP1 (Beta) and the program works fine now. BTW its V7.06. Thanks for the reply.
