I decided i would try to reinstall the plugins and system rokbox just will not uninstall. I get the message "Plugin Uninstall: Manifest File invalid or not found."
When i go in via ftp it isnt there and if i try to install it again it says it already exists! ahhhh - what do i do?
Fixed it - for anyone interested.
Go in via ftp and ensure rokbox in plugins system is removed and any consequent files (rokbox.xml and .php i believe).
Then you have to extract the system.zip and upload those files MANUALLY or it will not work.
