You are right ..... it seems that there is incompatible the installation of Dialogue and Private Messages at one time...
I installed private messages and later install dialogue and it began to give this error. I think that in some point come up and it causes mentioned error indicating that this file is absent.
I hurried asking to the forum without seeing well that was happening.
Thanks
