Sorry if this has been reported before but this is my 1st post and i'm new to the world of sccm
But when I try and run reports the following error occurs
The DefaultValue expression for the report parameter ‘UserTokenSIDs’ contains an error: Request for the permission of type 'System.Security.Permissions.SecurityPermission, mscorlib, Version=2.0.0.0, Culture=neutral, PublicKeyToken=***********' failed
SQL has been upgraded from express to 2008 r2
Anyone point me in the right direction as to where I should be looking at please?
