Looking for help recovering a missing project file in
Pinnacle Studio 12 Ultimate. When I click OK to open the .stx file, I get the
"Open Project, please wait" window briefly, but then it vanishes and the
timeline is just blank. Anyone have any ideas on how to recover or relink this
file?

Did you move content
Did you move content relating to that file around? or maybe even deleted any?
No, didn't move or delete
No, didn't move or delete any files. Went to open it and suddenly it was gone.
