Limit on number of videoscore downloads?

I have a free account and I have uploaded a few scores.

For free accounts, how many times per day can I download videoscores of my own compositions?

The reason I ask is because I tried to download my second videoscore in a day, and it doesn't seem to be happening.

So, if the limit for my case is 1/day, do I need to resubmit the request anew on a future date, or will it download itself automatically at the appropriate date?

Finally, I'd like to also know where this limit is documented. I have looked everywhere to no avail. Just curious.

Thanks in advance.
