Okay, if that sediment is the sediment from fermentation and the wine hasnt been racked off it yet then do so soon as those are called lees from primary fermentation (gross lees) and those can spoil, never go more then about 3 weeks on them before racking off them. Since there was no actual fruit in this batch its now where near as bad as if there was so not a big problem at all here. As far as adding cranberry goes, make sure you have the proper ingredients to add to your wine making list before doing so like the acid test kit and some yeast nutrient and energizer. Cranberry and Blueberry naturally produce benzoate which inhibits yeast and can make fermentation not start or just struggle so the addition of nutrient and energizer are recommended for basicall all wines but especially these 2 types. This is a list that I would get before starting your next batches of wine and these will be in your arsenal forever from now on.
