I am finding that downloads from Yandisk, which the plugin recognises although the URL is slightly different (e.g. [yadi.sk]) are failing with the error 'File Name not found'. They download successfully with a certain other downloader, so this is not just a dead link. Freerapid version 0.9u4, plugin version 1.0.3.

Thanks in advance for your help

Thanks for the report.

Fixed in plugin v1.0.4.
