First, sorry for my no perfect englisch! I am from Germany.

Today i installed the new version of xdsl, after a view things to handle it works.
After this i want to check if everything works well, i start my box in the normal mode
and the a message appears that the "Xbox l1ve-account was not reachable, try it later!"

I tried and tried! Nothing happens!

Is it a real problem with Xbox l1ve that they are down today or did something
happen when i install xdsl?

I installed the 50MB version via FTP.

For every helpfull message i thank you!

X-DSL shouldn't do anything that would interfere with Xbox Live. I suggest checking your Xbox Live network settings and trying again later.
