Time out while login in any IC role

Hi,

I need a help with a strange issue that occurred in my system.

Yesterday I was accessing it (a business role copy from the ICAGENT) that was working without any problem. I am in release 7.0.

I was making some screen configurations and now the business role doesn't upload... I get a time out. On the Internet explorer I see a yellow icon on the bottoom and if I double click to see details I get the message:

"document" is null or is not an object on:

http://<server>:<port>/sap(====)/bc/bsp/sap/crmcmp_ic_frame/header_jscripts.js

Any ideas???

Regards.
