Shareport works fine with 64 bit Windows (all versions, including '7'). There seems to be a conflict with another driver that is not programmed very well. You can find the crashing driver(s) in the eventlog. Virtual server software causes a lot of these BSOD's, since it installs a virtual USB driver. And that makes all other USB drivers crash.
So Shareport is not to blame here, start looking for the driver conflicting with it.
