Live Office error with Webi Integration

Hi,

I am getting the following error while I try to integrate my webi report into power point slide. I am able to connect to webi interface using live office from power point but when I try to access any report and select a block of the report it throws me this error.

Note that it was working fine but all of a sudden stopped working for everyone in the office.

does anyone know what could have caused this.

I have already restarted the Tom Cat services but no use, I have also tested this in all 3 environment such as Dev QA and Prod and getting the same error.

please see the error below. will appreciate your help.

Thanks
