I asked for recovery from the above page, but I could not send it because I could not attach a log file. When I output the log file from the mobile phone application, a file with extension ". Html" was output. However, the log file that can be attached to the above page is only the file with the extension ". Log". When asking the telephone support of "03 4578 0488", he was told to send e-mail to the following sales support. https://www.teamviewer.com/en/support/sales-inquiry/ And the answer was to vote for tickets here.
