Invalid Session ID error during QV reload

[#1]

Hi,

I have qlikview document that reads data from objects in Salesforce using SalesforceDLL.dll connector. Everything worked fine without any issue but recently after a dataload into the Salesforce Object when i tried to reload the document, I started getting the error "Invalid session ID found in SessionHeader.Session not found."

I have verified the Saleforce Org and the session settings are correct configured.

Can anybody throw some light into this.......

Thanks in advance....
