Please help,this error killing my time.

Please give us more information - don’t forget that we know nothing about your situation, except of what you tell us.

Did it work before? Or is it a fresh environment, suggesting that it hasn’t been installed correctly? Does it happen with standard reports as well? Did you try redeploying reports?
