Android market will not let me log in?

I signed up to the android market a year and a half ago, and it is randomly asking me to sign in to access the android market. Furthermore it is asking for an account with an email that i didnt use. It says my email is IRGtransient@youtube.com

I didnt even know that youtube had email accounts, and i never made one at that. IRGtransient is my youtube account but why is it asking for the password. I dont know the password because I never made an account, this is completely random. The account i originally assiciated with the android market is a gmail account. Can anybody help? I cant access the store
