TopHat thank you for your suggestion, I have now managed to add an administrator and access the admin console, my next issue is when the users try to search for other users within Spark I get the following error messages:
Unable to contact search service
If I go to actions and start a chat and input the users name here it will find them, and once a chat window is open they can be added to the rosta.
Any suggestions why they are unable to search normally
Openfire is on a windows server 2008 R2 Enterprise
Spark installed on users PC's running Win7 SP1
