Whle trying to download the 9.0 and 9.1 versions I keep getting the following message:        System extension cannot be used

The system extension "/System/Library/Extensions/AppleUSBEthernetHost.kext"was installed improperly and cannot be used. Please try reinstalling it or contact the product's vendor for an update.

Suggestions?

This isn't a message from our software nor is it related to our software. As for suggestions, you might consider to reinstall your operating system. The kernel extension (kext) you've named is provided by Apple. Sounds like either its damaged, or not the correct version. You could attempt using the recovery partition to run the disk repair utilitiies or reinstall the OS (this is generally not destructive and will try to fix things for you).
