Google Calendar Not Syncing Wuth Kies

So my calendar decided it was going to become absolutely useless and no longer wants to sync, or reminder me of bdays, or remind me of anything I set in it. Each time I hit edit event, a msg pops up saying "google calendars cannot sync with KIES. Use my calendar to sync with KIES". This is a new issue as I was able, in the past, to sync. I have syncing turned on, I checked in settings and everything is check marked for my accounts. Its so damn frustrating, ive missed friends and coworkers bdays because my calendar refuses to notify me. Any ideas? Thanks for the help.
