It send something but it returns error.
But I don't know it.
Windows Live Messenger 2009 Update
So, I was playing around with it again today and after digging a bit, stupid me found something and remembered....they DO have connection testers in the options menu. So, I decided to run them. Running a TCP test, it appears that I can actually connect to the server and data is able to be sent. So, it tells me I can use the messenger service. Well, no, not really. I put the password in and I get the same error saying that the service is temporarily out of commission. However, the connection troubleshooter caught my eye. Ooooh, let's click that! So, clicking on it and running the tests, which only seem to run part way BUT might be a huge breakthrough, it seems as though *for me anyway* that the default gateway test fails. It says that your gateway is offline. Now whether it's my service...or we're just missing a vital kernel extension, I don't know. However, it seems that may be the trouble we're having for getting it to actually connect to the service.
