vMap upgrade to 1.9.0 failure

I have just upgraded from vMap 1.0.0 to 1.9.0 and now get the following error in the backend when I go to Components > vMap.

1054 Unknown column 'sstatus' in 'field list' SQL=select `sstatus` from `#__vmap`

I could not find any instructions on how to upgrade so I just re-installed the latest package (pkg_vmap1.9.0.zip). Was that the correct way to upgrade?

Hello,
Please download and install the latest version i.e. 1.9.1, It will resolve the issue...

Hello Daniel,
All working fine now.Thank you very much.
