Hey guys, I have the SAME EXACT PROBLEM. I used to have Live when it first came out and now I bought ESPN NFL 2k5 and tried using the 2 month free trial, but I get "xbox live not found." I called MS about 5 times yesterday. I tried connecting with and without my router and both times I received the same error. I'm so frustrated because it used to work fine but now, unfortunately, it isn't. My ISP is Optimum Online which isn't compatible, but Opt. Online says they know for sure it works. I just hope we can find a solution to this and I'm sorta glad to know it isn't just me.
