Hello husem,
thank you for the bug report!
Could you please reinstall FV Player from this link? http://foliovision.com/downloads/fv-wordpress-flowplayer.zip To do that you will have to first deactivate and delete the current FV Player plugin you are using. WordPress will warn you that you might loose settings and data, but it’s not the case with our plugin, no settings now videos will be lost. Or you can just replace the plugin files via FTP.
Then the issue should be fixed.
Thanks,
Martin
