Envato Market Plugin issue

Using Envato Market Plugin v2.0
Working great except that it keeps telling me that one particular plugin is not installed but in fact it is installed.
So I can’t get any updates.
I tried a new token, the plugin author advised me to re-install the Market Plugin so I removed it (deleted it) and re-uploaded the plugin but it keeps using the old data so I can’t start from scratch.
Any tips?
