i'm just installed SDL Tridion 2013 SP1 and i have found a problem when i have started the application. I put a picture with the errors:

Probably, this error comes from a problem with the connection with the Tridion_cm database, because i saw an error in the Eventi viewer that says:

A database error occurred while executing Stored Procedure "EDA_TRUSTEES_GETTRUSTEETOKEN". Cannot open the connection with "Tridion_cm" database. Session start error with the user 'TCMDBUser'.

Could you tell me any configuration which is propably wrong?

Thanks in advance!
