I have vista home premium on a new pc, and just installed messenger live 8.01

For some reason i cant sign in with my usual sign in info, anybody else founds issues with this?

I found the solution to this and thought i would post here for others.

Apparently Vista's "auto-tuning" networking
feature doesn't play nice with some routers. Not sure if it is a bug in
Vista, a bug in Messenger or a bug in the router firmware but anyway this
looks like a possible workaround that might help other people who have the
same problem.

Try this:
- Click start
- Type: cmd
- Right-click cmd.exe when it appears under Applications
- Click Run As Administrator
- Type the following: netsh int tcp set global autotuninglevel=disabled
- Press enter
- Restart your computer

Nice tip Jcas! Thanks!
