Maximum number of devices reached !! Frustrating!!

[Eren68]

I can't install any apps because apparently I have too many devices registered to this one account........ I only have the one phone currently registered, as I have deleted anything else not in use. Anyone else have this problem? I'm trying to restore my 920 and I've got 57 apps that say 'Attention Required'.

I know it takes a while for some devices to 'de-register' but 7 or 8 days ??

Has anyone else experienced this? What am I missing?? Thanks.
