it looks like you are using a non-empty ObjectQualfier and I assume, that the installation procedure for the 3rd party module lacks of OQ support, Check your database for a stored procedure dbo.GetOnlineUserStatistics or dbo.UOR_GetOnlineUserStatistics and rename it to dbo.DS_UOR_GetOnlineUserStatistics

Sebastian,

I will post the solution on gemini, its been on my todo list for too long now :)

Angeles,

I am not sure what is going wrong. You are correct the stored procedure "DS_UOR_GetOnlineUserStatistics" is for the DNNSpired module, and GetOnlineUserStatics is for core module.   Both can exist without conflict.  It is odd that the error you recieved read that the stored procedure did not exist, but you have the stored produce in your list.   May I suggest you try to execute the store procudure through the managment studio. 

When I try to execute the stored procedure by clicking on the Generate SQL button in the MSSQL Manager I get the following error.

Error 424
	Object required SQLDMO must be installed on your server so that this option is available.
