Insync - Upgraded to Insync Plus. Force Restart Syncing

We have upgraded to a paid version of Insync as the free trial had expired a couple of days ago.
Insync appears to be working correctly through the Linux UI. However I know that it is not syncing as I have added files locally in the insync folder which it is not picking up and they are not appearing on Google drive.

There are not Errors showing or Actions required with in the insync window.

We are using Ubuntu 12.04 64bit
Insync version 1.2.11.35149

What is the correct procedure to resolve this and continue the syncing. We have a large number of files that have been synced already (2TB size wise) so moving these or reuploading these wouldn’t be an option

Many thanks

Hi @Richard_Aitchison sorry for the delayed response, any updates? It is still not syncing?
