Are you experiencing the "Node Not Found" issue in Premiere Pro?
Make sure your Film Impact plugins are up-to-date.
Sometimes a Premiere Pro sequence may get corrupt. The Film Impact plugins are trying to access certain specific data from a given render node — But find this node is no longer available.
Please try and fiddle with one of the parameter controls of the effect that generates this error.
That will usually solve your case.
