hitachi smart tv app

I have just got a hitachi tv with a deezer app pre installed and apparently acording to their app store its up to date 

But when i try loging in with my account it says im not conected to the internet.

Yes i have unpluged it and rebuted my router. And i do have internet on the tv as Netflix ect work fine 

Also the demo try function loads but wont play anything 

It i put the incorrect password in it tells me the password is wrong therefore it must be communicating with your server 

Any ideas
