rsfiles-download-manager header mistake

i am waiting for an answer on an rsevents problem, no-one has replied – seems the plugin authors are not visiting these forums…

Yeah, definitely does not install on 3.0.1 or 3.0.2

No problems installing any other plugins.

Same result every time
Starts with this…

Downloading install package from http://downloads.wordpress.org/plugin/rsfiles-download-manager.1.0.0.zip…

Unpacking the package…

Installing the plugin…

Successfully installed the plugin RSFiles! – Download Manager .

Then when you click activate plugin you get this…

The plugin does not have a valid header.
