symsnap.sys BSOD after NIS 2010 installation

I installed NIS2010 two days ago on a PC and see some symsnap.sys BSODs.

symsnap.sys looks like Symantec's StorageCraft Volume Snap-Shot driver.
Mine is currently at version 7.0.16

PC is running Win XP SP2 and has NIS 2010, Ghost 12, Acronis TrueImage Home, and a 3rd party online backup program.
I believe some of the above may use the Microsoft Volume ShadowCopy Service (VSS), and that may be causing a problem with symsnap.sys
I see "Volume Shadow Copy Service error: Volume/disk not connected or not found. Error context: CreateFileW(\\?\Volume{ ...." in my event logs.

VSS has not reported errors in the past.

 

I've temporarily suspended the online backup program (that appeared to be running at the time of the VSS error), and don't see any problems for now.

Maybe LiveUpdate fixed it.

I'll try to isolate/verify, and report back to this thread.

If someone knows a sure fix, please post.

Thanks.
