x2.3 lite problems

[rshorts]

I had an X2.3 lite installed in my xbox last week. When the xbox boots with the x2.3 lite turned on I get the Cromwell screen but it won't flash using my cd and just hangs. If I disable the chip I get the Microsoft error and the xbox stops(this not the error where it boots 3x it boots but halts after displaying an error in English Spanish and other Languages) I'm at a loss!
