Cant advance, stuck in an area.

I cannot enter the 5-letter code into the Medical Personnel Only, I have the correct code but only the first two letters work. The last three are stuck. This is frustrating as I have come this far to have to delete and reinstall the game???? This is the 3rd and a row that I have purchased from Big Fish here I get stuck and am unable to advance and had to remove the game. NOT HAPPY!!
