343, Can you reset my Custom Challenges...?

Alrighty, so when that Custom Challenge option come at on HaloWaypoint.com, I decided to test it out. Well, they had a max of like 60 hours or something, but I found a way to get past that, and typed in like 99 hours. I clicked accept challenge, and since I did that, everytime I go to the Custom Challenge page, it gives me an error with a lot of coding.

I messaged 343 on Twitter saying I got an error everytime I tried to go to the Custom Challenge page, and they answered back saying I should delete my cookies and cache. I did, and nothing changed. I messaged them saying nothing worked, and then they said I should chane my web browser to Firefox or Internet Explorer.

I figured out it was the 99 hours thing(Or atleast something is glitched with my account) because If I sign onto any other account and go into Custom Challenges, it works fine, and if I go onto any other computer, it gives me the same error.

So is it possible to get this fixed or am I never going to be able to create another Custom Challenge…?
