Error while loading project

[Saulo Soares de Toledo]

I tried open Quanta project on KDevelop, and I receive this error:

"Sorry - KDevelop; Could not load project management plugin KDevGenericManager."
"Sorry - KDevelop; project importing plugin (KDevGenericManager) does
not support IProjectFileManager interface."
"Error - KDevelop; Project could not be opened:
file:///home/saulo/....../quanta.kdevelop"


I compiled the code with no errors with your help (last post I send
some minutes ago). Something here I need do to work this project?
