In answer to my own question, I have got to the point of deploying the IMS package, but this doesn't seem to make any progress.
The deploying window comes up and after a short time, the browser says Done, but the web page is still deploying, with no indication of progress.
The package is from a Live Text VLE software package and is 700Mb in size.
I'm guessing this may have something to do with it.
Is there anyway I can check to see if the package is deploying and just needs more time. Do I need to make ajustments to the Moodle configuration for the size of the IMS packages?
Any assistance most welcomed.
