cgminer not working on deepbit.net I installed Cgminer and created the batch file to run it

cgminer.exe -o http://pit.deepbit.net:8332 -u myemail@gmail.com_workerName -p s3cr3t

but when I run it I get

[2013-05-21 00:39:34] Started cgminer 3.1.1  
[2013-05-21 00:39:34] Probing for an alive pool  
[2013-05-21 00:39:38] Pool 0 slow/down or URL or credentials invalid  
[2013-05-21 00:40:34] No servers were found that could be used to get work from .  
[2013-05-21 00:40:34] Please check the details from the list below of the servers you have input  
[2013-05-21 00:40:34] Most likely you have input the wrong URL, forgotten to ad d a port, or have not set up workers


Does anyone know what I'm doing wrong?
I'm the author of this question and it worked when I tried again next day.
