Your version of Olympus is out of date and needs to be updated. The current download is intentionally outdated because antiviruses tend to false-flag new versions when they're posted.

If it's stuck on "Checking for updates" in the Options & Updates menu, that actually means the update check failed. If this happens, try restarting Olympus a few times - it can be somewhat random whether it works or not.
