Corrupted file- Vray render disabled

Hi, I have an issue with my Sketchup Vray.

I could render all fine my scenes with light and materials and then suddenly I could not render anymore and this message would pop up : “ No output file has been specified. Animation frames will not be saved. Do you wish to proceed ?”

What can I do??? I have imported some models from the 3D warehouse, could some of them corrupted my file ??

Thank you for the help!!

Post the SketchUp model. It is rather impossible to infer what has happened from your post. Were you outputting an animation? Were you exporting to a folder or drive that is no longer available, like a disconnected USB drive?
