at the end of thw quest "old world blues" in OWB aftertalking to DR Klein when i leave the think tank my game starts on the loading screen and freezes if I leave before talking to him it's fine but I can't complete the dlc now so im stuck in the big MT

I JUST had that problem and i figured it out so for all of you that have this problem this is how i did it.
1. Clear system cache
2. Sleep for a while and cancel before your done sleeping
3. Create an new save file
4. Start the loading by going threw the door
5. Press the Xbox guide button and go up and down but not pressing anything
After I did this it went to the slides. So if this doesn't work for you just play around with stuff until it works or give up in frustration like I almost did.
Hope this helps!

you are soooooooo epic thank you

Hey guys, iv tried these steps afew (hundred) times and made a rage comic to release my stress! but it still wont work ill write down exactly what im doing so you can tell me if iv done somthign wrong

step 1: (from dashboard) go into system memory then HD and clear the cache
step 2: open the game from dashboard load up profile which is saved outside in big mt right infront of the two doors to the think tank/ the sink
step 3: go into the sink and sleep for afew hours and cancel before it finishes (take a buffout due to being encumbered)
step 4: make a new save
step 5: go from inside the sink into the think tank and the writting comes up stating dr klein blah blah.. [ok] <--- oh plus the xbox menu up down bit after this
step 6: go through all the dialouge and next is "leave the think tank"
step 7: at this stage it loads a whole lot longer before if blacks out and freeze's but it keeps doing it : /

i have tried it afew different ways to no sucsess and its giving me the blues..

after another 30 minutes it worked it seemed to work on scrolling the xbox menu afew times thanks for the help anyway sorry to be a pain!

Any time and happy playing!
