Unable to install any Metro Apps, error 0x80070003

Hi, I've just installed an SSD into my system and put a fresh copy of Windows 8.1 on to it. I've got the Program Files set to be on my normal HDD using an mlink junction, everything else is on the SSD. Everything works fine, except installing Metro apps, none of them will install, I just get the error 0x80070003. I'm not too bothered as I don't use them much but its just annoying

Any suggestions on what could be up, is it a registry change needed?

Many thanks
