Maps disappeared

After the last update today three of my four maps in use are disappered.
Initial the map was OK, after I add one placemark and made a refresh on the website to see the result, the map was no more visible.
I removed the placemark but no change, the map stays invisible.
Two other maps are also gone (unimportant), the fourth is still there ...
I did not use API keys, system Joomla 2.5 last update.

Hi.

You updated plugin (get last version), but not updated component!

Check updates, and you'll get your map back.

I hooked on the two updates on they arfe in the automatic update manager like I allways do, dis I have now to search for a manual updat ?

Press Purge Cache.
After that press Find updates.
You'll find it

Component have to be 5.5.0.0 - it is current.

My language is Dutch ... have to translate, just aminute please ...
