I got it as well, although in my case the barnacle folder got all wonky and now refuses to delete from the drive (Moving works ok; the usual fixes for deleting folders that claim they're not empty aren't working).
Most of the time if I rerun the update, it still gives me either the roots error, the 10054 Winsock error on srcds.exe, or a generic run-time error on srcds.exe.
It also seems to be happening on DoD:S as well, which is extremely irritating as I don't think any updates have even been released for that game of late.
Edit: I was able to eventually get it to take all the way through by moving the barnacle folder elsewhere enough times, although I still can't delete them all.
