Plenty of points but unable to download

Hiya.- I'm a little confused at the moment :(
I have more than enough points and on my home page it is saying i have downloaded 12 Roms today- I haven't!!!- I have more than likely tried to download that many times, but nearly everytime a notice is coming up saying I have reached my download limit so I tried again. I think i downloaded 3.
It started last night (no previous problems), so thought i would give it some time to maybe correct itself, but its exactly the same today too.
It varies, but its getting to about 28% downloaded, then just stops. Is there a limit to the number of downloads allowed each day which runs along side the point system?
I have never experienced this problem before, and massively happy with the site, but I dont know what to for the best next!!!

it is a bug, and seph is working on it.A download stopping prematurely is completely unrelated and is caused by an interruption in your internet connection. We suggest using a download manager to help avoid those problems.
