R1soft plugin does not work with latest version 5.1.29

Hi All,

It looks like the latest version of Interworx (5.1.29) breaks the R1Soft plugin.
This is causing massive headaches for myself and my clients.

Is anyone aware of a workaround or a way to fix the plugin?
Alternatively, is it possible to install older versions of Interworx (I can then disable updates, until the plugin is fixed).

Thanks in advance!
