Problem details: I'm failing to log into Bancho on my Windows XP SP3 computer. I'm using the latest version of osu!, and ProxHTTPSProxy with certificates installed when playing osu!. I can fetch seasonal backgrounds, check and download updates, see in the proxy logs that I'm connecting with servers, but osu! complains that my client is too old for online play. When playing on a certain private server connecting with the -devserver method, I can log in, but it the game about forged certificates (which might be the one reason) and when submitting scores I get an error that I'm using test signing mode and score submission is disabled (that particular server doesn't really care, but this might also contribute to not being able to play on Bancho).
