Recapturing Closed Account

I "closed" our "live" / "skydrive" account after purchasing office 365 as it became very confusing between the "free" and "paid" versions.  Doing this cancelled our entire live account, bing webmaster tools, etc and now it says my email address is taken which is what we log into windows 8 with on our computers, hence, I can't even "verify" my identity now.  Can't use another email address as this is my personal and business primary.   Any idea's to "reactivate" or "reregister" my email id with live.com??  thank you in advance.
