Unfortunately this problem exists at times when you have multiple veggie
files (.veg) on the timeline in a project. After a while when opening your
project, at times there are errors/difficulty getting it opened, like whats
happening to you.
There is no set solution, renaming the folder the project is in and moving it
to another location often works and even trying several times until you get it
open. BUT personally what i do is simply dont drop any veggie files in my
project timeline anymore, i just take the time to render out what i need and
then drop that on the timeline.
When im on a deadline and to have such an error, is stressful!
