There is not enough information here to give you an exact solution.
What operating system is running on the server?

Broadly, the cause of your problem is probably a combination of
1) not uninstalling Fb 2.1 properly; and
2) not installing Fb 2.5 properly

The solution depends on the operating system and the model of Fb 2.5
you want to run (Superserver, Classic or Superclassic).
