If I met with things like that, two things I will do:
1.check my computer.(sometimes the firewall may be doing the scan and take up all your memory or something else)
2.check my network.(exactly as Dave said)
If it still won't work, give up and try another day. You don't think it will happen all the time, right? :-)
Fortuantely, till now, such things have never happened to me.
------------- TO BE, OR NOT TO BE. IS IT THE QUESTION?
