Unable to load cookies with Pickle

[HiImNew]

Full Code:

>>> while True:
	from selenium import webdriver
	driver = webdriver.Chrome()
	import pickle
	cookies = pickle.load(open("cookies.pkl", "rb"))
	while True:
		for cookie in cookies:
			driver.add_cookie(cookie)
		break
	break

Traceback (most recent call last):
  File "<pyshell#1>", line 8, in <module>
    driver.add_cookie(cookie)

I have previously saved cookies with:

>>> pickle.dump( driver.get_cookies() , open("cookies.pkl","wb"))

It worked once, however now it is not working. I tried deleting the cookies.pkl file and recreating it again, but to no avail. Any help is appreciated.
