I don't really speak Spanish, but if I'm reading the error correctly, it looks like it's saying something about not being able to log in to the database. Is that correct? If so:
What type of database are you connecting to?
What type of connection are you using?
Is this a 32-bit or 64-bit application?
Is the OS 32-bit or 64-bit?
If you're using an ODBC connection, have you set up the connection as 32-bit for a 32-bit app or 64-bit a 64-bit app? (You need the 32-bit database client installed for a 32-bit app).
If it SQL Server, do you have the SQL client either version 10 or 11 installed? (Crystal will NOT work with the SQL Server client that's automatically installed with the OS (version 6.)
