My yahoo voice is not working! I had to do a system restore cause my Mom deleted all of my cookies and I lost?

my sign in seal with yahoo mail and couldnt get it back. So I did a system restore to the day before my cookies were deleted. It worked to get my Yahoo Mail back up , but I still cant get my Yahoo Voice to let me log on. It remebers my Id and pass word but it wont complete the log on process. The little face in my task bar is dead and it just keeps asking me if I want to try again. This has been going on for a week now and I would very much like to have that acess back. I just got the phone in and out and I am sure that I have missed very important calls.

I dont know if this is the fault of Yahoo or if it is my computer , but I am guessing that if my Mail account came back up and the Voice did not , when I restored the computer, then it is not the fault of the computer. I have looked and looked in the Help at Yahoo site and there is nothing there about Yahoo Voice Help. So if any one can tell me what the Heck is going on I would really appreciate it. Thanks.
