Unable to open Project file in timeline
I did a wee Video Ad in early January 2019 and tried to make an alt today 21-2-2019 and it just won't open in my timeline. I can see all the sequences and other files but I just can't get the project file to open in my timeline to work on it.
I thought it was due to a recent upgrade but no as I can open older files in it. One thing I did do was to copy the whole folder back from my back up drive and tried to open it from there. I even created a new file and it won't open from that folder either.
I am sure I have had this once before but I can't remember what I did to fix it. Any ideas? Pulling hair out!!!
