When I press on download panel, IDM shows error message "403 Forbidden" or tells that it impossible to resolve IP address of a host. Please also check IDM integration into your browser. Please update IDM to the latest version and restart your computer. This means that you use an old version of IDM. When I try to open a downloaded video file, IDM tells that the file is not found. IDM shows some error while rebuilding temporary files at the end of a download. IDM downloads only audio or video without audio part of a file. Please try to disable all other extensions but IDM, restart Chrome and look if problem persists.Ĥ.
