Until you can resolve the Kies problem, use this App to backup your text:
SMS Backup & Restore - Play Store
I don't recall if it does mms, so take a look at other Apps in the play store for that. If you need to also backup the call log, the above developer also provides an App for that.
Take a look at this Kies FAQ, hopefully it helps:
