Element not found in cache - Selenium (Python) - python-2.7

Question

I just wrote a simple webscraping script to give me all the episode links on a particular site's page. The script was working fine, but, now it's broke. I didn't change anything.
Try this URL (For scraping ) :- http://www.crunchyroll.com/tabi-machi-late-show
Now, the script works mid-way and gives me an error stating, ' Element not found in the cache - perhaps the page has changed since it was looked up'
I looked it up on internet and people said about using the 'implicit wait' command at certain places. I did that, still no luck.
UPDATE : I tried this script in a demote desktop and it's working there without any problems.
Here's my script :-
from selenium import webdriver
from selenium.webdriver.common.keys import Keys
import os
import time
from subprocess import Popen
#------------------------------------------------
try:
Link = raw_input("Please enter your Link : ")
if not Link:
raise ValueError('Please Enter A Link To The Anime Page. This Application Will now Exit in 5 Seconds.')
except ValueError as e:
print(e)
time.sleep(5)
exit()
print 'Analyzing the Page. Hold on a minute.'
driver = webdriver.Firefox()
driver.get(Link)
assert "Crunchyroll" in driver.title
driver.implicitly_wait(5) # <-- I tried removing this lines as well. No luck.
elem = driver.find_elements_by_xpath("//*[#href]")
driver.implicitly_wait(10) # <-- I tried removing this lines as well. No luck.
text_file = open("BatchLink.txt", "w")
print 'Fetching The Links, please wait.'
for elem in elem:
x = elem.get_attribute("href")
#print x
text_file.write(x+'\n')
print 'Links have been fetched. Just doing the final cleaning now.'
text_file.close()
CleanFile = open("queue.txt", "w")
with open('BatchLink.txt') as f:
mylist = f.read().splitlines()
#print mylist
with open('BatchLink.txt', 'r') as inF:
for line in inF:
if 'episode' in line:
CleanFile.write(line)
print 'Please Check the file named queue.txt'
CleanFile.close()
os.remove('BatchLink.txt')
driver.close()
Here's a screenshot of the error (might be of some help) :

Ok i didn't work with python but know the problem
you have variable that you init -> elem = driver.find_elements_by_xpath("//*[#href]")
after that you doing some things with it in loop
before you finishing the loop try to init this variable again
elem = driver.find_elements_by_xpath("//*[#href]")
The thing is that the DOM is changes and you loosing the element collection.
