Bug reports.

Downloaded Hota from the VKontakte group HERE. When launching, it asks to update the HD-mod, and when attempting to update, it displays the following error.

Indeed, there is such a problem. Apparently, since the release of 1.4.2, there have been changes in the HD-mod update system, and older versions are no longer updated. You can download HD from the website: https://sites.google.com/site/heroes3hd/rus/download, install it in the Hota folder (simply overwrite what is already there), and then update it through the auto-update.
