I am having major issues today with refresh. My reports are failing due to credentials but the credentials are not the issue. Here is the error message I am getting:
Failed to update data source credentials: Failed to connect to a database. Error message: Could not load file or assembly 'Microsoft.MashupEngine, Version=1.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' or one of its dependencies. The system cannot find the file specified.Hide details
