I have heard rumors, but not being an owner can't confirm, that the sockets that Mikhail likes to use are not exactly top shelf items. I have the same adapters, from the same guy and ironically enough talked with him just the other day about the issues that you are having. The pins being too long shouldn't be an issue, but I can't say for certain that it isn't. Sounds to me like you're getting a flakey connection like crappyjones was with his Extreme.
