WTH - weight gain???
Remember water is very heavy and if you retain water your weight will go up. If you are upping your exercise and only taking in your 64oz you are not getting enough water and when you don't get enough water your body will retain water. You probably need to drink more water. Also when you tear muscle apart (i.e. when you work out), it fills with water, so after a strenuous work out you are likely to retain some water. Make sure you are getting enough protein too, that helps with muscle recovery and protein is vital to the weight loss process. Protein First!
Agreed with the other posters - its probably water. Remember that 32 ounces of water weighs 2 lbs. You are not eating less than 1000 calories and gaining fat. Just keep telling yourself that. Play it in your mind like a broken record.
Make sure you are getting plenty of water - 64 ounces is a minimum not a goal. If you have healthy kidneys the rule for proper hydration is 1/2 your body weight in lbs in ounces of water. I find that I dont lose if I drink less than that. Your body will start trying to hold on to what it has if you are getting less than that.
Also, jump your protein up - You need that to rebuild the muscles you are tearing during exercise. If you are really working out hard, every bite you eat needs to be lean protein.
Finally, don't let it stress you - every one of us has gone through this. It is a perfectly natural, normal thing (hear Eugene Levy say that in your mind). The stress is a killer, if yo get too stressed step away from the scale for a week.

What they said above... Also, relax, stress is not good for you. I have been stalled for 3 weeks and this morning I stepped on the scale and had gained a pound! I am 12, now 13, lbs from goal but I'm not going to let it stress me. My calories are less than 800 a day, protein around 80, 70-80oz water and less than 50 carbs. I know I'm doing everything right so I'm going to just keep working at it and wait for the stall to break. I walk 1-2 miles every night but can't do much more than that because I have a torn meniscus in my left knee and it kills me to walk more. I have to take 2 aleve's an hour before I walk just to be able to walk what I do. The muscle you are building weighs more than fat and it will also start burning more calories once it stabilizes.
