I can't deploy a solution

I installed April CTP 2005 in a new computer and I can't deploy an existing solution which works in the old computer.
When I deploy it give me Error -1056899072 with no messages.
If I make a new solution then it works fine.
I'm sure the problem is with the datasource. Because when I try to deploy with june CTP give an error: "no se ha efectuado ninguna asignacion entre los nombres de cuenta y los identificadores de seguridad" and in English is like No mapping between account names and security IDs.
Any ideas?
I don't want to fix all by hand
Thanks in advance.

I have defined roles for cubes. Then you must validate each member of the role with the user accounts.
Hopefully I can deploy the project.
