Error creating project

[admin]

Hi,

we accidentally deleted the directory of a project. We have backups of all the jobs, so now we want re-create the project again with the same name.

First I have executed the following command:
"delete from UV.ACCOUNT where @ID=PROJDS_MKT_INT"

Now I have the following error when Im trying to create the project in the Administrator Tool.

"DSR.ADMIN: A schema called PROJDS_MKT_INT already exists. This must be dropped before the project can be created."

Does anyone know how to delete all the references to the project to create the project again?

Thanks

Antonio Monteiro
