Thank you very much, but how would I go about doing either of these things?

Google “MegaDownloader” and/or “VPN”.

YoungJaaron said: What causes the download limit?

Mega imposes it.

YoungJaaron said: Does buying the Pro Plans not work?

I’m sure it does work.

YoungJaaron said: Also, I’m halfway through downloading all of the files (47 left to go). Is there a way to start using MegaDownloader without having to restart all of my progress?

Once you get hold of MegaDownloader, you should be able to work out how to download files selectively.
