Hello. This morning I find that my version of NOD v4 is unable to update its definitions. The ESET Threatcenter shows that version 5509 are available, but my installed NOD is showing 5507 as the currently installed definitions version. Attempts to manually update result in a message that an update is not necessary - that version 5507 is the most current version. I know this isn't correct. I've attempted to clear the cache as is described in the knowledge base. But this still results in NOD telling me that the updates are current at 5507. Can anyone please advise? Thank you.
