Yeah,I had some kinda problem with mine, a part on my id,but it took 3 months for me.
Did you take it into DHS yourself,or did you just mail it in?
I took mine in and paid upfront,they gave me a reciept which works temporarily and then 3 months later got my card.I was kinda panicky too,but some of the oregon MJ forums were useful they let me know it takes awhile and stuff.
