Issue with Bigfoot Killer card

Anyone else having issues with their Xeno Pro network cards? I am currently running Windows 8 64bit, and every once in a while the network card will stop working upon boot-up. It just takes a restart and it functions again, but it's a pain. The current software running is, and there is a newer version out I have upgraded this in the past and the network card loses all ability to function.

Was wondering, if anyone else has experienced this?
