Can't get pass the logon screen

Hi!

I'm working with WDSc for Iseries and I'm webfacing applications right... 
I pretty much figured out how it works and I got pretty good result too! 
until sundenly, something terrible happened!

I can't no longer retreive data from the webfacing server. I mean... I 
click on the cmd, the logon screen appears and I enter the name and 
password and it starts to load... forever! Nothing is returned to my 
browser. I know the Webfacing server is started and (apparently) works (if 
I do not enter the good password it promps me again). 

Now if someone has a clue about how to solve this problem please help me 
because all my ressouces are expired :( 

Thank you

Simon
