Missing files but no red screen ?

Hi,
When I want to export my film to a master file I get a message that some titles, effects or generators are missing or deconnected.
Actually I don't have any red windows and everything is running fine.
Is there a way I can search or find which file FCX is referring to ?
Should I just export to see what comes out ?

Thanks,

I have seen this and reported to Apple. Exports are fine in all cases. I think it's a corruption somewhere in the project file.

Try deleting the generated library and event files thru FCPX choosing ALL render files. Then export your project (which will render upon export much faster than timeline rendering). Let us know if this solved the problem of the error message being displayed.

Fine. I will try that and keep you posted.
I did export not withstanding the warning and it did export properly.

Thanks
