Can't get the M2Tech Hiface Drivers to download

Every time I go to the Hiface website and attempt to download the drivers to my Mac the only thing that downloads is the installer package itself, not the actual drivers. Anyone else have a similar problem? Months ago I did this with ease but later fried the unit in a thunderstorm and the Mac stopped recognizing the unit, so now, with the new modified unit from John Kenny I cannot get the Mac to accept the new drivers - only the installation package. I have tried to download the drivers from the Geek website but have not been able to get that portion of their website to come up.

Anyone with similar issues that got resolved?
