Last time this happened i posted my Ticket number and someone who monitors the forums fixed it for me.
Have just installed on a 5th PC and have a 5 licence key and it says i need to buy a new licence when it's only installed on 4 devices.
If i leave it to regular support the ticket as per last time get's updated or looked at in several weeks. If i post my Ticket number here will it be looked at kinda soon?
Cheers!
