Just to let everyone know that it appears Digi-Key supplier links have stopped working with CircuitStudio, presumably due to a change at Digi-Key because there hasn't been an update to CS that I know about. I'll post a workaround/fix if one becomes available. Of course these are the element14 forums so I should really suggest using Farnell/Newark as your supplier 
.
Update -- it seems the Digi-Key API used by CircuitStudio has been retired and won't be coming back. Please post below if you have been affected to give Altium some indication of the urgency with which a new software release will be required.
