A rite of passage of all Revit users I guess
Create a project yesterday, will not open today - 'Data in file corrupt... must be manually recovered.... Contact Autodesk Support' (which I've done).
3 Backups same and only one journal file - which I tried dragging and dropping on the Revit icon (amazing trick that... wish I could work as fast as the journal replays itself )
Anyway, the question is - can you interrupt a journal file to stop it short of the point where it exits, presumably because of the corruption - in my case very nearly at the end?
