I did set up a free account with Mega and have signed in using that through JD2. I understand that there is a limit but I was expecting it to limit to 5 gigs/6 hrs or something like that and not based on the file size itself.
I tried to turn off CDN but got a bandwidth limit exceeded immediately.
The website will start the downloads but once it reaches bandwidth limit it stops. Not sure if it will start up again but testing that now.

Update: I left a 7.6 gig file to run using chrome today and it appears to have completed properly which included a 6 hr break. JD2 itself though still will not start the downloads.
