Plugin shoing update in Joomla but does not downlo

In Joomla the ZH GoogleMap plugin is showing an update is available. But when I try to update it says the link does not exist. If I download the latest version and update it still says the update is available.
How can I fix this issue?
Will a new update be available soon to fix this?

Hi
I fixed it. Just try to do again.

PS I'm rebuilding distribution package, ie I will use package instead of component in JED. And after a while I will remove plugin and module from JED as separate extension. Finally you will have only one record in JED with all of extensions (component, plugin and module). I decided to do this for case I develop system plugin (which will process contact page), and other plugins.
And yesterday I deleted plugin zip file

Excellent. I confirm this is now working fine.
one install sound like a good idea as you always want to install all 3 anyway.
Great product and look forward to seeing new updates

Many thanks
