Since my brother and I updated to the latest version, we are unable to voice chat. Audio wizard ran okay and my sound card drivers are current. We had no problems with V.5. If I request a chat and he accepts, message pops up " audio conversation with Dave has ended". It never connected, so don't know how it could end. If he requests a conversation and I accept, message pops up "we are currently unable to set up this conversation. Please try again later". Got no help from Tech Support at MS. Can anybody help 2 old people. Thank you.
