Another frequent error is that of an invalid link. The first thing you should do, if you encounter this problem, is to check that you have written or copied the link correctly. In most cases, this error is caused by a missing character in the URL.

For older versions of MegaDownloader, it may be necessary to use the domain mega.co.nz.
