When I try to use GP's or drachmas to purchase full protection, I keep getting the message that I've reached my limit for this item.  Since when ??

Hi! You probably have this Item already at your Market. Check both: GP and Drachmas tabs, 24h and 8h Items. If you have at least one Full Protection (No matter in which tab, or which duration), or you have one active atm, you won't be able to buy more.

Geez, okay thank you!
