All of a sudden my AC client seems to hang during the posture assessment: updating portion and after a couple minutes will produce an error: Posture Assessment failed: CSD library signature verification failed. I tried deleting the library from the local cache folder as instructed in the Cisco doc for the client user messages but still get the same result. The client has been virtually rock solid until yesterday. Win7 32 bit Enterprise; java 7.60; no recently installed updates. Thanks for any assistance!
