Worked perfectly for me ,but got the following error when trying to run/view a Report

An internal error occurred on the report server. See the error log for more details. (rsInternalError)

Could not load file or assembly 'Microsoft.ReportingServices.ProcessingObjectModel, Version=10.0.0.0, Culture=neutral, PublicKeyToken=89845dcd8080cc91' or one of its dependencies. Access is denied

Does any one have an idea on how to fix this
