Hi,
If you are referring to the odd times that Mega will freeze a DL try this:
If you get a 'freeze' do nothing to Mega
Hopefully you are using a vpn -- change location.
Refresh the page
When the page resumes - Mega should say you have interrupted DL, do you wish to resume. Obviously, pick yes.
The DL should continue. Also the change in location will reset the daily limit.
You can also use the change vpn method at any time that Mega says limit exceeded.
If these happen when you are not on a vpn just start one up then refresh.
