Vagex Viewer "Last video has no credits left, please use auto clear cache"

Hey guys,

Do you have this "Last video has no credits left, please use auto clear cache" problem with Vagex Viewer?
Because whenever I get this message, I don't get credits when viewing videos so I need to restart the application.

The thing is, I use auto clear cache and I still receive this message a few times per hour.

Any idea how to avoid that? (I'm using the latest version)
