The operation could not be completed because an error occurred when creating frame 0 (error -1)

Gosh, after using FCPX for 3 months with no hiccups, I'm having problem after problem. Here is the latest issue. My sequences won't export. I get the following error message:

The operation could not be completed because an error occurred when creating frame 0 (error -1)

Has anyone dealt with this?

Try trashing your render files. Usually it's one of those that is the culprit.

Go to "File" then "Delete render files" then select all not unused.

Hope that was it. Otherwise you can use preference manager from digital rebellion to trash your prefs, it's free.
