Failed to instantiate file from module

Hi, I created a new webpart inside a module with other webparts that were already there. I also created a new feature.

When I try to activate the feature I get a message:

Failed to instantiate file "webtv-Medias.webpart" from module "WPRedirection": Source path "Features\FTV.Intranet.Solution_FTV.Intranet.WebTV.Medias\webtv\webtv-Medias.webpart" not found

What is weird is that this webpart is not even inside the module "WPRedirection"

Any ideas pls?

thanks
