Service Unavailable

Dear Guru,

I've just upgraded my ABAP and JAVA kernel and patch level of my CRM 5.0. However, after I enter transaction CRM_IC, the browser gives me "Service Unavailable". I look at SMICM, it is running. The service in SICF is also activated.

Appreciate if anyone could help me on this. Thank you.

Rgds,
