Msn messages will not send anyone of my contacts?

it started off happenin very rarely but now it is happenin constantly. i will try to start a conversation with sum1 and the message will appear in the sent/recieved message box but the contact does not actually receive it. how do i stop it happening? sum conversations will work but others will not. also it will not allow ther messages to *** through most of the time.

also i have a small problem with the messenger signin me out at random times. if u can help wit that at 2 i wuld be grateful.

hi
there could be several reasons for that problem
do this first
close MSN
then go to
start menu
control panel
add an remove programmes
MSN
'change'
when the wizard appears select 'repair'
wait until the wizard finishes
sign in again

check if you have some kind of virus, (scan your pc) if you are running a p2p (emule, ares) ,these use a lo of bandwidth when runnign full speed, .. (in this case, slow down the p2p and restart the router) ..
check if you installed a skin, scipt, plugin, animated display or sth. recently .. that might be the reason ..
check if the versions MSN is according to your operating system and hardware
