When I try to install an add-on on LSPDFR (for example, EuP Law And Order), everything loads fine, but halfway through the download, it stops and tells me: "No network connection." When I click the resume button, it says: "The site is unavailable." I'm in Russia (maybe this is somehow related), and I have a normal internet connection.I never close the site until it's finished loading. What should I do?
