Google Maps plugin - Not working?

Hi guys,
Have a small issue, just wondered if you could shed some light on this for me. I installed Google maps when I installed all the other plugins but it appears to not be correctly working.

Not sure exactly whats going on but when I do try to load any map in an event, it comes up with javascript not found or something missing.

Not sure where I went wrong, I know I had to remove the events plugin in which was connected, which has now been deactivated and using another events manager plugin.

Removed the plugin manually from plugins screen from site admin, uploaded the file to install but same effect.

If you could point me in the right direction would be much appriciated,
