Can't insert webi object to LiveOffice using Webi wizard

Hi,

We are  using MS Excel 2010 and BI4.1.

LiveOffice can connect to BI4.1 Server, also can refresh  existing LiveOffice reports.

But when I tried to import a Webi report to Excel, it hangs. I also tried Universe query, it has the same problem.

Could you anyone please help. 

Thanks,

Youqin
