Yesterday i also had a problem. There is no reload that i saw but reloading from the main page should give you a new one.

I need to get past these captchas too and even though I've gotten pretty good with it and have a 90% success rate I don't feel it's necessary if you've implemented 2 factor authentication.
We're adding a form under the profile right now to disable the captchas. They appear before you login so we can't make them go away but if you activate this feature the captcha can be left blank (or wrong).

I just spoke with one of our coders and he's adding that in as we speak. It should be available within a few minutes. I don't want to say 100% incase he runs in to any unforeseen issues but it is almost ready.
You can also disable it without enabling 2 factor authentication.

For more information on our 2 factor authentication check out this post or onlyoneTV episode 22

Edit: might be a couple hours yet but it's coming.

Glad you were able to get in. The captcha switch is still coming. They're coding away at the moment and working down the list towards it.
Can't wait to turn it off myself.

I have had a lot of trouble with the Tradehill login captcha as well.  I've wondered why they didn't just use a somewhat standardized captcha such as http://www.google.com/recaptcha.

still doesn't work says I'm a bot   is this going to get fixed haven't been able to get in for days!

i never once had the captchas problem. it's always the case the looking at the letters very carefully, but i'm pretty much stating the obvious

FYI, the captchas have now been marked as optional by tradehill.
You can disable them in your profile. 

Captchas are good...but there is always a way around anything.. just set up a free pron site and have your viewers solve the captchas for you.  I heard the guys who make concert ticket scalping bots use a method something like that...grab the image, get someone else to solve it, then have your bot post the solution back.
