Question

i recently bought a new laptop (toshiba) with vista on it. i downloaded windows live messenger beta, but when i try to sign in it comes up with "signing into windows messenger failed because the service was temporarily unavailable. please try again later. Error code: 8100030d"

now i did research the problem hoping to find a solution, and i have been told over and over to download programs like regcure and uniblue registery booster. I did exactly as i was told but still the same code comes up.
