Our workstations are using Nicm.sys version dated 1/8/2008 11:27 AM, is there a more recent version available?

I would like to try updating to fix a blue screen issue on XP using client v.4.91 SP5. The memory dumps point to nicm.sys as the driver causing a deadlock. When I search through the downloads I do not see any nicm.sys updates.

WinDBG says:

If there are no newer versions available what are repercussions of going back to an older version, ie v3.0.0.4 in SP4?
