MarketPress - Size limit on digital downloads

I am experiencing an issue with two digital downloads we have for purchase.

- They are zip Files
- One is 170MB in size the other 212MB

All other products download fine (they are 156MB and less). I even deleted the product and created a new one thinking the database might be corrupted.

When clicking on the order download link, it goes to a screen saying "Webpage not found" then after a couple of seconds, switches to another page saying download limit of 2 has been reached.

I've input the direct links and the downloads work just fine, so it's not a server issue.

Was wondering if MarketPress has a size limit to digital downloads?

Thanks in advance.
