[Res]Problems while renaming service

I believe I have determined what is causing this. It seems to be caused by renaming the new service that has been added. It seems that this then causes the null pointer exception and prevents the request editor from being displayed. Trying to delete the affected service freezes the GUI as well. To get around this it is necessary to restart SoapUI Pro and then the service is deleted. It seems that something is potentially getting corrupted as well since if I re-add the REST Service the resource and request from previously are automatically added again, which shouldn't be the case as I deleted the parent object. The 4.6.3 build seems particularly flaky in this regard. I am at a dead stop presently since I need admin rights to uninstall and reinstall SoapUI Pro to see if this resolves the problems and the only people that have admin rights are now on annual leave for the holidays. Also, checking the installation directories shows the previous installs of 4.6.1 and 4.6.2. Shouldn't installing future updates replace the previous version rather than install alongside the earlier version(s). Could this have caused the issues by way of a shared configuration file perhaps since all versions are now behaving the same?
