12.1.2015 Intrusion Prevention Signatures "not available"

So I was having an issue with some of our machines on 12.1 where it was not showing the current sigs in SPC management and causing the big red X.  Noticed that it was a known issue, so I put a couple of our machines on 12.1.2015 (ru2) as that seemed to be the fix.  Unfortunately, is been 24hrs now and those two machines are still showing under the intrusion prevention signature column "not available".  Ive run LiveUpdate on them a couple of times but to no avail.
