'More than one download at a time' problem

I was downloading a NDS ROM about half an hour ago, my computer crashed crashed. I tried to re-download, and the page says I currently have a download going and I don't. I saw on the board that some others have had similar issues, but I haven't seen any advice other than to get a premium account. Any help other than this?

The system sees you as still downloading- it doesn't anticipate your computer crashing, what you could try is resetting your internet, if that doesn't work, wait for 1 hour and it should be fixed

Thanks - will try.

I get that too, it usually takes around 30 minutes after a download has finished for it to let me do another, I think it's just normal and not a problem.
