Loading Error in NWBC in TM 9.0

Hi,

I am able to go to NWBC in TM 9.0.  I could see the overview of my resources. If I try to display one of my resources, it is still loading. I am not able to Define resources from NWBC.  Is there any setting in NWBC to correct this error ?

Another question.Most of the transactions in TM 9.0 are enabled only in NWBC. Is there any option to use only SAP GUI instead of NWBC in TM 9.0?

Your input will be appreciated.

Thanks.
