After deleting projects, resources still seems to have assigments

[Makenia]

Hi,
We have set up the server MS Project 2002 and we have
introduced an Enterprise Resource Pool.
Initially we have being creating some projects to test the
functionality, and now we are ready to start working for
real with it.
We have delete from the server all the assignments, all
projects, all tasks, etc.
We seems to have an error, as when from MS Project
connected to the server and going to the option on Tools
Create Team from Enterprise, some resources seems to have
still some assignments.
The availability that a show is like if they still have
assigned some work to do.
As well as the graphics shows that they are already work
to do.
Many thanks,

Makenia
