ESS on EP -SP9 using ITS server

HI

I install EP SP9 & Import the ESS Business package & able to use the package , screens.

But every time i click on the links i.e Personal Information --> Personal Data ( the data get's displayed ) & if click on the link Address , it disconnects SAP login & re-connects once again, it happens for all the links on ESS package

Thanks
