Did you check your spam folder? I have problems with some of my emails always going to spam even when I designate the sender as not spam. I am sure they are very busy but I do not know of another email. You could send it a second time and double-check the spelling in the address. 

If they are working on it they will propbably have it done very soon. At least you have herd from them. When they fixed mine they said they would either fix it this week or the next week as the weekend was coming up. We should not play yet anyway so do not panic
