My console has not allowed me to connect to Xbox Live for the past week. I've recently transferred my profile from its hard drive to a USB storage device and think this may be related to the issue somehow. I have ensured that all wires are fully working and have no problems with my network connection. When I test my Xbox Live Connection the "Test Status" reads: Network - Connected, Internet - Connected, Xbox Live - Failed. When I try to connect I am prompted with the following message - "Your console can't connect to Xbox Live." and the error code "8015190E". When I search the code: 8015190E - I am brought to the following page: http://support.xbox.com/en-US/xbox-360/errors/error-code-8015190e - which states that my XBL account is blocked?? I have tried all the solutions on Xbox.com (such as clearing my system cache and removing the previous update) to solve this problem and have had no success. I'm really annoyed at the shoddy service I have so far received from Xbox Support. When I try to connect to Xbox Live on my brother's console with HIS hard drive I am given an update to download. When I try to download the update I am given the following error status code: 3f4b-0000-0080-0300-8007-2751. I haven't a clue what's going on and I'm getting really tired of Microsoft's constant, ambiguous issues.
