Hello, 

I installed and activated my theme on a temporary domain rm9.301.myftpupload.com through go daddy word press admin, when I then changed the domain to the one I had purchased staycasa.co.uk i got a message saying i had to register my theme.. when I try register it just says 'The purchase code already has been registered. Could you deregister purchase code on the another domain and try again.'

I changed the domain back to the temporary one and deregistered the theme code, then switched the domain back to staycasa.co.uk and it still says 'The purchase code already has been registered. Could you deregister purchase code on the another domain and try again.'

Please advise the solution?
